Dunno if I count as straight or bi. I tend to date females but, if, for example, my gf was actually a guy the whole time I probably wouldn't mind either (I'd be pissed at being lied to though XD). I also find some men attractive.
As for stuff like gay people kissing, I don't care if gay dudes kiss. I get weird about gay chicks kissing though. But that has less to do with gay coupling and more to do with being cheated on by a girl twice. Also been cheated on by straight girls so regular couples kissing also bothers me
