Guess you're not because as a gay guy I find that to be one of the most offensive claims I've ever heard (and I'm not just targeting this towards you. You're sadly not the first person I've seen with these opinions). To assume that gay people just about throw themselves towards anything defined as male with no sense of self-control or self-respect (or, hey, a thing called standards and visual preferences) is A. ridiculous and B. arrogant, at best. As a person who has served in the army and has showered with pretty much all my close friends, let me tell you that the experience was completely neutral sexually - albeit sometimes hilarious for different reasons but lets not get into that.
To assume a guy like me would just go gaga over, well, basically nothing is absurd and insulting.
