From the content of your post it seems like you are well versed in what sexually arouses a homosexual man. Either that or you're just plain stupid and think that all homosexual men are hypersexual and want to fuck any and all guys at all times.
Aren't there much more important things to be worrying about than sexual orientation?
Gee, let me think about this one here for a second.
Sexual arousal of a homosexual man. Other men and their genitals.
See how easy that was when you add 2+2. Was it really that difficult?
Let me know when you get it. Give yourself a pat on the back in the meantime.
Also, there are more important things to be worrying about. Of course. But why add to it? Are you really missing the point? There is male on male rape in every branch of service. When you're stuck in a valley doing 180 degree security or on mission, you create a bond with the guys in your squad. It's that simple.
You're out there, on edge all the fucking time. All of a sudden another guy comes on to you. You have a loaded M4 with Surefire lighting, vertical grip, and Aimpoint Red Dot. It's not a pretty situation, but that's how you have to be out there. Any little thing that threatens you sets you the fuck off.
