Because I enjoy drawing it? Just because I draw toons in underwear doesn't mean I wanna fuck those toons in underwear. It's something I've been doing since long before I even had a concept of sexuality. It's completely divorced from sex for me.

Whether or not someone is physically attracted to people doesn't limit what we're allowed to draw, do, or enjoy. Asexuality's like any other orientation. It's part of who you are but it doesn't dictate your whole personality or how you draw. And I do hope you won't take this as an attack, but that's kind of a weird thing to say to someone celebrating their identity during Pride, you know? ¯_(ツ)_/¯

And if you didn't know, then you do now, no harm done, and we all learned something here today. Have a good one.
