I've come out 3 times now.
1. My sister: totally accepting, she realised I was ace long before I did, and suggested it to me (and I completely ignored her). She's fine with my aro-ness as well.
2. My best friend: accepted, but I don't think she understands. She was pretty much like, "Ok, cool." I pranked her once and hacked my friends Skype and told her I was gay and had been seen kissing another friend. She completely freaked out and started caps-locking-me-out over skype. Not sure what that means. Why would it matter if I were gay to her so much?
3. A random friend who asked if I were gay: I said no, I'm asexual. She assumed that that included my romantic orientation as well since she has no idea they can be split. She laughed as if I told I joke and I said, "I'm serious. I'm asexual. I'm not attracted to anyone. I've never had a crush before." All she said was, "We'll see." That's pretty much the equivalent of, "You just haven't met 'THE (right) ONE' yet!" response, haha.
