So as an Ace/Demi person in the NSFW field, I wanna talk about something thats kinda always debated on and makes general assumptions about Ace people.
Is an Asexual Person still Ace if they engage in sexual activity or do NSFW content? My answer and belief, Absolutely Yes.
1/?

Asexuality states that a person does not find any sexual attraction in any person.
So this leads to two things, 1) because they do not feel physical attraction that sparks arousal, why have sex?
Or, 2) Well sex is more about stimulation and intimacy, so could I do it?

Now this is just speaking on personal view on being part of the Ace Spectrum (Demi. Attraction is made on comfort and connection), If my romantic partner wants to have sex, and I'm in a good state, I'll say yes. Being in chronic pain now sometimes makes it tricky but anyway-

Point is, sex, attraction and arousal do all exist in the same field, but are not solely connected,
You dont lose your identity as Asexual if you engage in sexual activity you are comfortable with.
Looking at and enjoying NSFW art doesn't either.
Self stimulation doesnt either.

It comes down to how you personally are wired when looking at someone and what your physical response is,
Sex is always, ALWAYS, your choice as an individual.
Want it? Cool.
Dont want it? Also cool.
It aint gonna revoke your identity and never will.

Have fun and be happy~
