Lots of guys, especially in the fitness realm, seem to be o.k. with guy on guy stuff. They're hot. They like being hot, and dig a hot guy now and then, and....a decent prostate massage / fucking. I have met LOTS of guys that are incredibly good looking, in great shape, great jobs, and willing to go either way over the last few years. I think once a lot of guys find out you're o.k. with it, they open up about it.
Lots of athletes are know are pretty open about going either way, and, a lot of times, downright forward ("Damn, Chuck, you hot and pumped up today!") They aren't queeny, whiney, etc, but, typical guys who happen to get down with guys sometimes. They know they are hot...and have a good time with it.
This, of course, still doesn't mean the jerk off test doesn't apply. If you're gay, you probably jerk of to guys, and vice versa, but, in my personal experience, lots more guys are ok with getting with another guy to pleasure each other.
I had a friend who told me he was mostly straight who begged me to hit the sack with him, several times. I did. A month ago, he got married to beautiful gal. I told him that I hope he gets at least the 58 years my parents had.
I think gay for pay is kinda' bullshit, but, many a gay man has said "Here, exploit me."
