I've always wondered, since most anime and manga have girls with huge cough cough upper parts, and such. It doesn't have to be a main character, and he/she can have a romance with someone, but just is not attracted sexually to anyone and not wanting to have that in a relationship. I don't shoujo where it's under 18 friendly, so there wouldn't be that content, but the character is actually asexual.
Thanks 🙂
