The gay accusations are ridiculous
Every time 2 males have some sort of bond people shout "gay." I mean come on, it's clear Prince is obsessed with his boss, but it's to the point of worship. When he knocks the guy on the ground and asks them to "remember what he did for us" it's clear that Ben Wade did something for him(probably bring him out of his boring poor life) and make them all wealthy, living what they consider a good life.
People even criticized his choice of clothing saying he was more "stylish" than the rest of the gang(meaning he wore a button leather coat) which is bordering on pathetic. In the end, Prince draws his weapon because his intuition finally tells him that Ben didn't want to be helped and was about to kill them all. If he really did have these gay feelings for Ben do you think he would have drawn his weapon to kill him? I have absolutely no problem with homosexuality, but there's no need to force it where it doesn't belong.
Ben is his boss, he's his boss's lieutenant, it's strictly platonic.
edit: By the way, people claiming that Foster added a feminine act to his performance, check out 30 days of night. It's pretty much the same performance amped up, it's just his style.
