Why are gays so "gay"?

I always wondered why every gay/bi guy I've seen acts like a "pussy"/"gay". I'm bi and I don't display that but whenever I'm with my friend (she's a gril) and we go into subjects like guys, dicks, sucking, taking and/or sex I start acting a quite a bit gay, I don't mind it, just think its a bit odd.
