Lost mine to my scoutmaster.
I get it from my mom all the damned time. My dad is actually asexual and he sticks up for me. I think my mom is worried that I'll become a nun like her great-great aunt, but being a nun doesn't interest me. My doctors actually tell me I have nothing to be concerned about, since I'm not married, and love the fact I'm not engaging in sex with many people.
Actually, if you're asexual, nun isn't a bad gig at all. Free housing, food, opportunities for travel, time to study, get to help other people, strangers are automatically polite to you just cause you're a nun. If you're not keen on having sex then why the hell not?
