Unlike women, men are just beasts to be used in war and the worst jobs, like gay porn. It's nice to see these guys having sex they would never have in private.
I'm reading the complaints about the top's disinterest. Well, as someone who has blown my fair share of "straight" dudes, this is often how it goes. They don't usually go from "I only fuck pussy" to impassioned interaction with a dude. Sure, that happens. But more often it's an exchange of mouth and cock with as little emotional contact as possible.
