Heroes are important. Heroes tells us about ourselves.
The first time I heard the term 'asexual' was as an insult /accusation from my former abusive partner, convinced I'd betrayed her by letting her think I cared about her. According to her, my love was meaningless without sex, and I couldn't possibly care about someone if I didn't want to be physically intimate with them. It's taken me a while to move past that and see 'Ace' as an empowering term, but I'm starting to see it as part of myself, not a deficit but maybe even something to be proud of.
