Just because some one is smoking hot, and constantly putting it on display, doesn't mean they are someone you would want.  I spent time in the military, lived with a bunch of guys, shower, eat, sleep, and work.  There was one that I am told was the "most gorgeous man on earth" by more than one person.  He has the personality of a brick, and was about as bright.

Would I watch a video of him getting down with another guy, Yes.  Would I want to be the guy, NO.

For the original poster, I am guessing that none of these guys see you as anything more than a friend, and more likely just another team player, and that is the reason you show interest, but not desire.
