are there any (preferably free) online courses on sex ed that you'd suggest for teens? i'm not sure which ones are good
I don't know about online courses, but I do know a lot of resources you can look over about specific topics!
Many of these come from planned parenthood, which is overall a very good resource in terms of sex, reproduction, and related concepts.
WARNING: Some of these sources use pericisbinary normative language (ie; referring to people with vaginas as "women", referring to people with penises as "male", etc), so be mindful of that going in. I tried my best to find MOSTLY gender-inclusive sources, though.
Anatomy & Sex Terminology
[PT: Anatomy & Sex Terminology /End PT]
Here are some discussions of peritypical anatomy (apologies for the use of "female" and "male"):
Peritypical penis & wolffian duct [link]
Peritypical vulva & mullerian duct [link]
Let's get into sex hormones. When describing the hormones of someone, rather than using gendered language, it is best to use the terms Androgenizing, Estrogenizing, Micro-Androgenizing, Micro-Estrogenizing, Androestrogenizing, and Micro-Androestrogenizing.
-An estrogenized hormone profile is when the body prioritizes its response to estrogen or manually receives estrogen, meaning the person will develop estrogenizing characteristics. This often includes breast growth, widened hips, and a higher pitched voice. A micro-estrogenized hormone profile is when the body has a minor but noticeable response to estrogen, meaning they will develop some estrogenizing characteristics.Â
Someone Expected To Estrogenize (SETE) describes a person (perisex or intersex) who is physically or societally expected to naturally estrogenize during puberty. This could be micro-estrogenization, average estrogenization, or hyperestrogenization. Sometimes, this expectation may be inaccurate, if the person has unpredicted hyperandrogenism (high androgens) or hypoestrogenism (low estrogen).
-An androgenized hormone profile is when the body prioritizes its response to androgens or manually receives androgens, meaning the person will develop androgenizing characteristics. This often includes phallus growth, higher muscle mass, increased body/facial hair, and a deepened voice. A micro-androgenized hormone profile is when the body has a minor but noticeable response to androgens, meaning they will develop some androgenizing characteristics.
Someone Expected To Androgenize (SETA) describes a person (perisex or intersex) who (without the influence of HRT, physical damage, or tumors) is expected to androgenize during puberty. This could be micro-androgenization, average androgenization, or hyperandrogenization. Sometimes, this expectation may be inaccurate, if the person has unpredicted hyperestrogenism (high estrogen) or hypoandrogenism (low androgens).Â
-An androestrogenized hormone profile is when the body prioritizes androgens and estrogen near-equally or in fluctuating amounts, or manually receives varying levels of both. This means they will develop a mixture of androgenizing and estrogenizing characteristics - which could cause any combination of secondary sex traits. Micro-androestrogenizing describes the body having a minor but noticeable response to both estrogen and androgens, meaning they will develop some androestrogenizing characteristics.
Someone Expected To Androestrogenize (SETAE) describes a person (perisex or intersex) who (without the influence of HRT, physical damage, or tumors) is expected to androestrogenize during puberty. This could be micro-androestrogenization, average androestrogenization, or hyperandroestrogenization. Sometimes, this expectation may be inaccurate, if the person has unpredicted hypogonadism (low sex hormone production).Â
-Someone Without Puberty Expectations (SWPE) describes a person who (without the influence of HRT or tumors), is not expected to experience any puberty. This is usually due to having bilateral gonadal agenesis, gonads that are fully streaked and/or too small to produce sex hormones, or similar variations.
We are currently in progress of creating the intersex visual guide, which will be out on October 26th this year, so keep an eye out for that It goes VERY in depth about intersexuality, and we hope it will become a very popular resource!
(Volunteers are still desired, reach out if you're interested! [link])
In the meantime, here are some sex terminology:
-Perisex (sometimes also called Endosex or Dyadic): A person/creature with the most commonly viewed natal sex traits within their species. For humans, this includes SPETE and SPETA.
-SPETE (Someone Perisex Expected To Estrogenize): A perisex person with XX chromosomes, who natally developed a vulva, two average-sized (or large) ovaries, a single average-sized (or large) uterus, two fallopian tubes, and (without the influence of HRT, physical damage, or tumors) is expected to estrogenize (at a typical range) during puberty.
Their vulva will have two labia minora with a clitoral hood, two labia majora, a single pea-sized clitoris, a single moderate (or deep) vaginal entry, and a urethra between the vaginal entry and the clitoris. It may or may not have a hymen that surrounds the vagina, covering it minimally.
-SPETA (Someone Perisex Expected To Androgenize): A perisex person with XY chromosomes, who natally developed a moderate (or large) penis, two moderately-sized (or large) testicles within the scrotum, an average-sized prostate, two vas deferens, two average-sized seminal vesicles, and (without the influence of HRT, physical damage, or tumors) is expected to androgenize (at a typical range) during puberty.
Their penis will have a phallus, a scrotum beneath the phallus, foreskin protecting the head of the phallus, and a urethra on the tip of the penis. It is straight or slightly curved when erect.
-Cosexual: A species whose perisex standard is being capable of both fertilization and egg production at the same time. (Ie; Snails, slugs, certain fish, etc.)
-Dualsex: A species whose perisex standard is having mixed sex traits, typically both a penis and a vagina, though other combinations may apply as well. This usually refers to fictional species.
-Intersex: A person/creature with natal sex traits (as in, sex traits that are not from physical damage, surgery, or HRT) that do not fall within their perisex norm. Usually this refers to natal primary sex traits (sex chromosomes, sex hormones, genitalia, and/or reproductive organs), but some people consider natal secondary sex traits (breasts, nipples, etc) to be intersex as well.
In humans, intersex describes the following:
-Mixed genitals.
-Mixed reproductive organs.
-Small/absent/undeveloped/hidden genitals.
-Small/absent/undeveloped reproductive organs.
-Split/duplicated genitals or reproductive organs.
-Penises or vulvas with an atypical appearance (ie; genitals that have a urethra higher/lower than typical, a vulva with a urethra or anus that merges into the vagina, a scrotum that is around or atop the penis, a penis that is curved downwards when erect, etc.)
-High levels or sensitivity to sex hormones.
-Low levels or sensitivity to sex hormones.
-Unresponsiveness to sex hormones.
-"Mismatched" sex chromosomes.
-SRY-negative XY chromosomes.
-SRY-positive XX chromosomes.
-More than two sex chromosomes.
-Less than two sex chromosomes (0X).
Dysex: A person with atypical primary sex traits caused by non-natal events (ie; labial hypertrophy from pregnancy, gynecomastia from fatness, a person with hyperestrogenism from tumors, etc), minor atypicalities in primary sex traits (ie; a minorly bicornuate uterus), or atypical secondary sex traits (ie; extra nipples, no breasts, etc) who does not feel as though the label of "intersex" fits them. This is considered the grey area between intersex and perisex.
Ersex: A person who is unsure of whether they are intersex or perisex, due to physical events that could have changed their sex traits. (Ie; A person who had an accident that could have potentially injured their ovaries, and they have no way to tell if their low levels of estrogen are a result of their accident, or if they have an intersex variation that causes hypoestrogenism.)
1- Perisex, intersex, dysex, and ersex are not labels a person can "transition" into, as they describe natal sex, not internal sex identities. So a perisex person cannot "transition to intersex", an intersex person can't have their intersexuality "removed" from them through procedures, etc.
2- A lot of people think that the terms AMAB/assigned male at birth and AFAB/assigned female at birth can be used interchangeably with SPETA & SPETE. But the reality is that intersex people get assigned male and assigned female all the time, and that AGAB doesn't actually explain anything about a person's anatomy.
Additionally, it also doesn't tell you anything about how someone was raised, because some people are assigned male but later reassigned female, assigned female but later reassigned male, assigned male/female but later reassigned as neither (ie; a cultural gender), or just raised in opposition to how they are assigned (ie; a parent disagrees with a doctor about their kid being AFAB, and socially imposes maleness on the child instead.) AGAB only communicates one thing - what is written on a birth certificate.
You can read more about the misuse of AGAB here [link.]
Sexual arousal, sexual attraction, libido, & sexual activity
[PT: Sexual activity, sexual attraction, libido, & sexual activity /end PT]
Sexual arousal vs sexual attraction vs libido:
Sexual Attraction is a sexual desire for someone/something. This generally includes a desire for touching/groping and/or enacting kinks/fetishes that provide sexual pleasure.
Libido describes a body’s physical desire for sex. This differs from sexual attraction, because sexual attraction is directed at someone/something, meanwhile libido is the body craving sexual release. Libido and sexual attraction can align for people who experience both, however they can also occur unaligned.
Sexual Arousal describes the body’s physical response to touch in a sexually sensitive area, or the body’s physical response to sexual attraction or libido. This includes genital arousal (wetness, erections, heat, etc), and/or physical responsiveness elsewhere in the body (ie; blushing.) A person can experience sexual arousal while not experiencing sexual attraction or a libido spike (ie; a person who is accidentally touched on their crotch may grow aroused, even if they do not find the person who touched them to be attractive.) Arousal is not the same as desire, as a person can be aroused and distressed or uncomfortable by their arousal.

Here are some resources about penis-in-vagina sex:

Guide to vaginal sex [link]
Note 1: "Breaking the hymen" is a myth. Penetration should not "break" anything. Peritypical hymens stretch and loosen, not break.
Note 2: Vaginal penetration should not hurt or cause bleeding. It may be mildly uncomfortable initially, but that discomfort should not remain. If either of those things are happening, it means one or multiple of the following:
-You do not have enough lube and/or aren't fully turned on.
-There is some type of sexual dysfunction going on.
-There is an intersex variation in play. Here are some vaginal & hymenal variations that are often noted to cause complications with penetration:
>Vulvar hypospadias positioned close to the vaginal entry (a urethra that is directly above or side-by-side the vagina) or persistent urogenital sinus (a vagina & urethra merged together), in which case the urethral tissue might be getting irritated by penetration.
>Vaginal hypoplasia (a shallow and/or narrow vagina)
>Imperforate hymen (a hymen that fully blocks the entry).
>Microperforate hymen (a hymen that only has a small entrance).
>Sleeve hymen (a hymen with excess tissue, which might block the entry.)
>Septate hymen (a hymen that stretches across the middle of the vagina, giving the impression of two or more vaginal entries.)
>Transverse vaginal septum (a non-hymenal wall of tissue that is horizontally blocking part or all of the vagina.)
>Longitudinal vaginal septum (a non-hymenal wall of tissue that vertically splits the vagina partially or fully into multiple entries.)
>Obstructed hemivagina (a non-hymenal wall of tissue that starts off horizontal but curves upwards, creating a pouch inside of the vagina.)

Note: If you go from anal sex to a different type of sex (ie; anal to vaginal), swap condoms first! You don't want to carry bacteria from one part of the body to another.
Always use the bathroom after sex (of any kind)! It decreases risk of UTIs.
[PT: Sexual dysfunction /End PT]
Here is a breakdown of sexual dysfunction:
Orgasm Disorders are disorders where a person experiences difficulty orgasming, or is unable to enjoy orgasms (for reasons unrelated to physical pain.)
-Sexual Anhedonia/Pleasure Dissociative Orgasmic Disorder is when a person feels little or no pleasure during an orgasm. Their body physically reaches an orgasm (ie; releasing fluids, muscle contractions, possibly moaning/whimpering/grunting, etc,) however the pleasurable chemicals in their brain don’t release.
-Anorgasmia is when a person is unable to orgasm, despite being sexually stimulated.
Ejaculation Disorders are a group of conditions that cause difficulty releasing semen at appropriate times.Â
Typically, ejaculation can be actively withheld for at least 4-8 minutes (or longer) of active continuous stimulation - for people with PE or DE, this is not the case.Â
Premature Ejaculation (PE) is when a person unintentionally releases semen too early into sexual engagement (under 3 minutes.)Â
Delayed Ejaculation (DE) is when a person cannot release semen until 20-25+ minutes of continued sexual engagement. This could be mild (experiencing ejaculation under specific circumstances), moderate (only ejaculating during oral sex or intercourse with hands), severe (only ejaculating when masturbating), or most severe (being unable to ejaculate at all.)
Retrograde Ejaculation (RE) is when a person’s semen flows into the bladder, instead of out of the urethra, during an orgasm. This makes it appear as if they aren’t ejaculating at all, since it doesn’t exit their body. This condition doesn’t cause physical harm or pain, as semen dissolves on its own within their body, however it can make it difficult to impregnate others.
Sexual Arousal Disorder is a condition where a person experiences sexual arousal, but their genitals fail to respond to it, making it difficult or impossible to initiate comfortable sex.Â
Female Sexual Arousal Disorder (FSAD) is when a person with a vulva cannot become efficiently aroused; either they produce too-little lubrication or their vagina fails to relax. (Personally, we think this should be Vulvar Sexual Arousal Disorder, to avoid the unnecessary gendering.)
Erectile Dysfunction/Impotence is when a person with a penis cannot become erect. Their penis may fail to get erect at all, or it may only get partially erect.
For people with either FSAD or erectile dysfunction, the sensation in their genitals (or nipples) might also be dulled.
Sexual Pain Disorders: A group of disorders that cause physical pain during sex or after sex.
Dysorgasmia is when a person experiences pain during orgasm, usually in the abdomen area.
Sexual Headaches is when a person experiences headaches during sexual activity. These headaches could be mild, or they could be debilitating. It could last anywhere from a few seconds - 72 hours long. Preorgasmic Headaches are when headaches occur mid-sex, before an orgasm occurs. Orgasmic Headaches are when headaches occur during an orgasm. Postorgasmic Headaches are when headaches occur after an orgasm.Â
Genito-Pelvic Pain Disorder/Penetration Disorder is when a person experiences difficulties related to penetrative sex. This includes dyspareunia and vaginismus.
Dyspareunia is when a person experiences pain during penetrative sex. This pain could occur on the outside of the genitals, the inside of the genitals, or in the pelvic area.
Vaginismus is when a person (with a vagina) is incapable of relaxing their muscles enough for comfortable penetrative sex (with an object of penetration that otherwise would suit the size of the canal.) Vaginismus has nothing to do with the size of the vagina, but is rather about the vagina being fully incapable of allowing anything of any size inside due to muscle contraction, or being so tight/clenched that it hurts (dyspareunia.)
Postorgasmic Illness Syndrome (POIS) is when a person experiences illness or disorientation after an orgasm. Symptoms may include difficulty understanding language or speaking, difficulty focusing, difficulty with memory, confusion, depression, anxiety, severe dizziness or lightheadedness, severe physical weakness, severe muscle or stomach pain/aches, excessive sweating, allergy-like reactions (congestion, sneezing, itchy or watering eyes or nose, dry throat, etc), and body temperature changes. These symptoms usually begin within 30 minutes post-ejaculation, but in some cases, they could be delayed for hours or even several days post-ejaculation before starting. This could last anywhere between an hour - 2 weeks.
Postcoital Tristesse/Postcoital Dysphoria is when a person experiences emotional distress after (consensual & desired) sexual activity. This could occur after any type of sexual activity, or it could occur in specific types (partnered sexual activity, masturbation, orgasms.) This distress cannot be related to specific kinks/fetishes, or else it would fall under a paraphilic disorder instead. Symptoms may include apathy, despair, guilt, shame, anxiety, panic attacks, frustration/annoyance, anger, or mood swings.
Spontaneous Orgasms is a condition where a person orgasms unexpectedly, without any sexual stimulation. These orgasms could be pleasurable, bland, or uncomfortable/painful.
Persistent Genital Arousal Disorder (PGAD)/Persistent Genital Arousal Syndrome (PSAS)/Persistent Genital Vasocongestion Disorder/Restless Genital Syndrome (ReGS) is a condition where a person’s genitals are constantly or frequently aroused, even though the person does not desire sex. If a person with PGAD has sex or masturbates, their genitals may calm down for a short period of time, before the arousal flares up again. Their genitals will be erect, swollen, hot, or wet.Â
UTIs, STDs, lubrication, protection, & birth control
[PT: UTIs, STDs, lubrication, & protection /End PT]
Some information about UTIs (urinary tract infections):
UTIs are infections in the urinary tract (urethra, bladder, ureters, and/or kidneys.)
UTIs can have no symptoms, or they can cause pain/burning while urinating, strong urge to urinate, cloudy urine, strong-scented urine, blood in the urine, pelvic pain, nausea/vomiting, and/or fever.
If UTIs are recurring, they can damage the urogenital system. Recurring UTIs can also sometimes cause urethra swelling or prolapse, which means the urethra will jut out of the genitals.
Here are some resources about STDs (sexually transmitted diseases):
What are STDs? [link]
Safer sex [link]
Here are some resources about lubrication:
Types of lubricants for sex [link]
Can you use coconut oil as lube for sex? [link]
Notes:
1- Lubrication is very important to prevent injury and discomfort. Not all vaginas produce sufficient lubricants, and anuses usually do not produce any lubricant at all.
2- Oil-based lubes can stain fabric and certain ones (like coconut oil) can damage condoms/protection and latex, so be mindful of what lubrication you use. Oil-based lubes can occasionally damage toys as well. Silicone lube damages many sex toys. Water-based lubes are the only lubrication that are safe for both toys and condoms alike, so they are often the preferable option.
3- Always make sure to check about allergies when it comes to protection and lubrication. The last thing you want is an allergic reaction, especially not in your genital region!
Here are some resources about protection and birth control:
How to pick the perfect condom [link]
Note: To get the size correct, measure your (erect) circumference in millimeters and divide that number by 2. That should be the correct size.
How to use an internal (vagina) condom [link]
How to use or make a dental dam [link]
Birth control methods & options [link]
What kind of emergency contraception is best for me? [link]
Notes:
1- Protection is highly recommended no matter what type of sex you are having. Use condoms, dental dams, and medical gloves and (if you have a functioning uterus) consider whether or not you want to try birth control on top of that.
2- If you decide to start hormone-based birth control, make sure you have your estrogen, androgens, progesterone, sex-hormone binding globulin, and albumin levels checked first. You could be hormonally intersex and unaware, in which case hormonal birth control could have disastrous effects on your body.
3- Hormonal birth control is often used for reasons other than preventing pregnancy. It may also be used to regulate menstrual cycles, or given (consensually or coercively) to intersex people socially imposed as female who are not estrogen-dominant with the intention of estrogenizing them.
[PT: Menstruation & pregnancy /end PT]
Here are some resources about [peritypical] menstruation:
What is menstruation? [link]
What is a normal menstrual cycle? [link]
Symptoms of menstruation [link]
PMS symptoms & cramping [link]
PMS vs PMDD - what's the difference? [link]
How to use menstrual hygiene products [link]
Notes:
1- Having debilitating pain during menstrual cycles is a sign of a menstrual disability. Typical cramping is uncomfortable, but it's not unbearable; just a nuisance.
2- Severe nausea is also a sign of menstrual disability.
3- Menstruating does not require blood. A person who is estrogen-dominant that doesn't have a functioning uterus still will often experience menstrual cycles. This isn't universal, but it is common.
This means that intersex people without uteruses, peritrans women without uteruses, and perisex enben without uteruses who start estrogenizing HRT may begin to experience all the symptoms of a period. Same for people who have had a hysterectomy - the menstrual cycle may stop for some, but continue for others. Do not assume that menstruation = blood, or that menstruation = uterus.
Here are some resources about [peritypical] pregnancy:

When it comes to kink and sexual etiquette, I recommend these:
The New Topping Book (in pdf form) [link]
The New Bottoming Book (in pdf form) [link]
Note: When it comes to kink online, make sure you tag your content properly and add trigger/content warnings. If you are afraid that tagging it directly will get you found and banned, then just write the tags on the post itself, and put the kink content under a "read more" cut.
Important notes about hygiene:
-Clean your sex toys every time! Obviously after use, but it's smart to also clean them before use as well! Be mindful of how you clean them, as some are sensitive to certain chemical components, and be sure not to use soaps that will mess up your PH balance.
-Speaking of which, be careful of what soaps you use to clean your genital region! Find PH-balanced soaps if possible, or only clean with water. And do not clean *inside* anything (vagina, urethra, anus, etc.) Your internal body cleans itself, using soap in it will cause damage or infections.
-Its a good idea to wash your genitals before and after sex. Be sure to wash the creases of your foreskin/the clitoral hood (if you have any). You don't want gunk building up in there.
Consent & sexual violence
[PT: Consent & sexual violence /End PT]
-Fully informed and communicated. Everyone involved is in full agreement, and is aware of what they are saying yes to. Ask questions about any uncertainties to be sure that everyone is on the same page, especially if kink is on the table.
-Not manipulated. Do not use guilt, blackmail, social status, or take advantage of someone's vulnerability in order to get what you want.
-Not initiated while intoxicated beyond the degree of being in their right mind. Light intoxication is more nuanced, but if a person is so intoxicated that they don't fully understand what is happening, then they are incapable of agreeing to sex or kink in the moment. If you *both* are equally intoxicated, then that's different - not necessarily *safe* (you may forget or misuse protection), but not inherently advantageous of each other.
-Not initiated while a person is having a psychological episode that leaves them unable to sufficiently communicate. If they do not fully understand you and/or you do not fully understand them, then engaging cannot be consented to.
-Not initiated while unconscious, unless they specifically agreed that you may act while they are unconscious. (Do note that consensual sleep sex is illegal in many locations, but legality =/= morality. For example, some places still have certain forms of BDSM illegal. Doesn't mean BDSM is morally wrong.)
-Reinforced/capable of being revoked without bitterness or irritation. Ask every so often "is this okay?" or establish safewords or safe signals (ie; snapping fingers, saying "red light", saying the word "octopus", etc) that signify to stop. You are allowed to feel disappointed that it ended, but do not take that out on the other person and make them feel bad for withdrawing consent.
-Not involving unagreed upon force.
-Not involving unagreed upon change of protection. Removing or sabotaging protection without the other partners awareness or agreement is a form of assault.
-Certain neuropsych disabilities leave people unable to consent. For example, some autistic people are capable of understanding sex enough to consent, while others are not. It just depends on the specific manifestation of disability they have. If they can sufficiently communicate to you , then they can consent (note: communication doesn't have to be verbal. It can also be nodding, shaking head, using AACs, etc. As long as their communication is distinct and understandable, and they understand you, then you can both exchange consent.)
-(Chrono) Minors can only consent to those within their own developmental range. For example, it is predatory for a 15 year old to engage with a 10 year old, but it is fine for a 15-year-old to engage with a 13-year-old, and a 10-year-old to engage with a 12-year-old. A good rule of thumb for minors consenting is 3ish years.
-(Theriform) Animals cannot consent.
-(Theriform) Corpses cannot consent.
What are the forms of sexual violence (SV)?
Sexual assault/SA: When a person touches you in a sexualized manner, forces/coerces you to touch them in a sexualized manner, or forces you to use a sex toy without your consent. Usually this is directed at the genitals, butt, breasts, and mouth, but if a person has a kink for other areas of a persons body (ie; feet), it may involve that as well.
CSA (child sexual assault) describes SA against minors, typically from adults. COCSA (child-on-child sexual assault/abuse) describes SA against minors, from other minors.
Rape: A form of sexual assault where penetration (of a phallus, object, tongue, or fingers) and/or oral was forced/coerced.
Sexual harassment: When a person makes sexual commentary about someone without their consent, makes sexual gestures at someone without their consent, creates or shares sexual content of someone without their consent (ie; nonconsensually taking photos of someone dressing), shows someone sexual content (ie; porn) without their consent, gives a person sexual objects (ie; sex toys) without their consent, and/or coerces a person to engage with something for the sake of sexualization (ie; giving someone a popsicle for the sake of fantasizing about oral sex without their consent, making someone blow up a balloon because they have an inflation kink, etc).
Sexual abuse: When a person repeatedly assaults, rapes, and/or harasses someone (rather than it being a one-off incident.)
