I received a request to write an NSFW Alphabet for the NPCs, so I went ahead and wrote it!
Please note that this is a long post.
For reference, Liana and Kyle are engaged, Maya is a lesbian, and Daniel and Paul are pansexual. I excluded Amber because she is asexual.
Paul: He holds his partner silently until they fall asleep. His embrace is warm and the sound of his heartbeat is loud, so you will feel very stable.
Daniel: He likes washing or massaging his partner. He wants to touch his partner more.
Liana & Kyle: Before falling asleep, they talk to each other, play pranks (cute things like pillow fights), and make plans for the future.
Maya: She likes taking a warm bath with her partner.
Daniel: He has most body part fetishes, as long as they are within normal limits.
Liana & Kyle: each other's whole bodies
Maya: Partner's smiling face
Paul: He had a vasectomy.(Because monsters can get pregnant with each other.) And he also has a large amount of cum.
Daniel: He always carries condoms.
Liana & Kyle: They are currently using contraception, but since they are planning to get pregnant after marriage, it seems likely they will have unprotected sex then.
Maya: She is a lesbian and does not want sex with men, so I will exclude this.
Paul: He likes seeing his partner cry.
Liana & Kyle: Liana said she wanted to peg Kyle, but he turned her down.
Maya: It doesn't seem like she has any particular
Paul: He's 450 years old and has had a lot of sexual experiences and partners. I'm sure you all understand without me going into detail.
Daniel: His body count is 30.
Liana & Kyle: They are each other's first partners.
Maya: Her body count is 3.
Paul: Missionary, Doggy Style, Standing Position
Daniel: Doggy Style, Spoons
Liana & Kyle: Missionary, Doggy Style, Lotus
Maya: To fingering her partner.
Paul: Sex with him would be filled with his partner’s shock and excitement, so it probably wouldn’t be humorous.
Daniel: Ever since a joke ruined the mood, he doesn't joke around during sex.
Liana & Kyle: They have some really cute and sweet conversations while having sex.
Maya: She hardly says a word while having sex.
With the exception of Harrison(The detective who spoke with MC on the phone), none of them have body hair.
Paul: I don't recommend taking a playboy seriously.
Daniel: He might get on your nerves sometimes, but he'll be a great partner. You'll have a good time with him.
Liana & Kyle: They have a very close and healthy relationship.
Maya: She isn't one to express her affection with words. But she'll do a lot of romantic things for you.
Paul: He has many sex partners, so he does not feel the need to masturbate.
Daniel: He tends to satisfy his sexual desires with his partner when he has one, and through exercise when he is single.
Liana & Kyle: They do it in front of each other for foreplay.
Maya: She doesn't like this. She tends to have almost no sex drive when she doesn't have a partner.

Liana & Kyle: Each other's very existence
Maya: Emotional stability,
This is something they have in common: Defecation, permanent physical injury, blood
Paul: abandonment/neglect play
Paul: His tongue is forked like a snake's. He'll give you a very sensuous oral experience. If you receive oral sex from him, you will want to run away within 5 minutes.
Daniel: He's not very good at oral sex, but let's try teaching him. 😏
Liana & Kyle: They are neither good at it nor bad at it.
Maya: She is good at oral sex.

Paul: He enjoys this very often.
Daniel: He was fired from his previous job for attempting quick sex.
Liana & Kyle: There were a few times when I had quick sex at MC and Lianna's house when MC wasn't there, before MC returned.
Maya: She has never had quick sex because she prefers to caress her partner slowly and for a long time.

Liana & Kyle: They prefer stability over thrills.
Maya: She wants to avoid risks as much as possible.
Paul: Just like finn and Jack, he can do it all week long.
Daniel: He prefers to do it twice during quickies and once when he takes his time.
Liana & Kyle: They have to do it twice to be satisfied.
Maya: She feels that once is enough. and She doesn't feel the need to have sex on a regular basis.

Daniel: He breathes heavily. The sound isn't that loud.
Liana & Kyle: The sounds they make during sex are incredibly loud.
Maya: She's very quiet during sex.
I don't really have anything to write about, so I'll skip this one.
Paul: When he takes off his clothes, he has difficulty maintaining his body's shape. His body turns into a smoke-like appearance. The same goes for the bandages wrapped around his face.
Daniel: He loves working out, you'll be blown away by how sexy he looks the first time you see his body.
Liana & Kyle: Kyle has many moles on his body. Liana likes to touch the moles on his body when he is asleep, saying they look like stars in the sky.
Maya: She doesn't usually dress up, so it isn't obvious, but when she takes off her clothes, she has a really great figure.
Paul: He has a sex drive as strong as Finn and Jack's. He wouldn't get tired even if he had sex every night, and he would be very satisfied.
Daniel: He has a strong sex drive, but he has his own way of satisfying it.
Liana & Kyle & Maya: Their sex drive is neither high nor low.
Paul: He is always awake at night. He will keep staring at your sleeping face until you wake up.
Daniel: He falls asleep as soon as his head touches the pillow.
Liana & Kyle: It takes them a while to fall asleep even after they've had sex.
Maya: She has trouble falling asleep, and the only time she sleeps well is when her partner is by her side.
