For example, one time I complimented a friend on her nails and another person in the room responded by seriously asking "Are you gay?" I responded "Yeah, why?" because it really didn't relate to the conversation and this ignorant little rat responded "Because, only a gay man would care about a girl's nails. I support gay marriage, though."
Other than that, I'm pretty confident and comfortable with my homosexuality that I really don't mind people asking if I'm gay.
I'm gay so... I know sometimes it can be a bit offensive because people use it as an insult, but it's what I am so... I use to respond with "yeah, but I'm happy... And it's a gay friendly country so **** off"
