*dial tone noises*

No worries at all, I think this is something that a lot of people get caught up on! Asexuality isn't very commonly talked about in terms of actually explanations, so a lot of folks tend to have the impression you did.

Asexuality is a spectrum that often correlates with but isn't actually inherently linked to comfort with touch! Asexual people can be sex-positive, sex-neutral, or sex-repulsed—or a combination of those three things depending on the context and their feelings at the time. I always write Alastor as aromantic and asexual, but I play around with his comfort levels regarding all those things depending on the fic or even how he feels in the moment, oscillating between sex-positive to fully touch-repulsed (or sometimes both, which causes some complicated feelings for him). (There are also demisexual and graysexual people but I'm just going to talk about asexuality here.)

I think a key point to understand is that for an asexual person to have sex, they're just going to have different reasons from an allosexual person. Alastor is never having sex in my radiostatic fics because he thinks Vox is hot and is super attracted to him (unlike Vox, whom I write as allo and who pretty consistently thinks Alastor is hot and wants to fuck him). Instead, some of the reasons he's slept with Vox in my works include: curiosity; societal pressure; nonsexual enjoyment of kink; sexual enjoyment of very specific acts (again, still not the same as "being sexually attracted to Vox"); seeking intimacy; being under the influence; etc.

hetero- different, other

heterochromatic - having multiple different colors (Angel's eyes)

heterogeneous - consisting of different kinds of things, mixed (jambalaya)

heterosexual - attracted to the opposite sex (Niffty)

homo- same, identical

homogeneous - consisting of the same thing throughout, uniform (the Exorcists)

homosexual - attracted to the same sex (Vaggie)

bi- two, both

bifurcate - to cut in two pieces (what Adam did to the Hotel)

biannual - twice a year (what Adam changed the Extermination schedule to)

bisexual - attracted to both same and different sexes (Charlie)

pan- all, evey

pancultural - across all cultures (the demographic in Hell)

pansexual - attracted to all genders (Blitzø)

a- without, lacking, not

atyptical - not normal (Alastor)

anemia - not having enough red blood cells or hemoglobin (Alastor)

asexual - without sexual attraction to others (Alastor)

aromantic - without romantic attraction to others (Alastor)

allo- other, external, variety

This one is hard, because there are tons of scientific uses of allo- that don't fit the pattern we're working on here.

Just know allo- is the opposite of a- in this case.

allosexual - not asexual, experiences sexual attraction

alloromantic - not aromantic, experiences romantic attraction

demi- partial, half

demitasse - a small (half) cup for espresso (what Lucifer probably owns but shouldn't use)

demigod - a being of partial divine status (Charlie?)

demisexual - literally means "partially sexual" but practically means "develops sexual attraction after building a connection with someone"

grey-

This one isn't a prefix. It's a portmanteau.

Husk and Alastor have a battle of wits, drinking, and jazz. AKA how I think Husk found out about Al’s situation.
