I have yet to tell any of my family or friends that I'm asexual. I have a feeling that they'll think I'm just making excuses for not being able to get girls. Especially because I used to date one of the girls in our group. Though we broke up because I wasn't moving fast enough for her. So maybe that'll lend credence to it.
It's all natural. I think the reason people ask that is that it's bleached.
