Not being a man I have absolutely no qualms over how far two straight men go in their affections. If both men are content with it, they can kiss, cuddle, whatever. Being a woman, I know that I'm allowed to hug and cuddle with my female friends with no feelings of shame or embaressment and so I think it's ridiculous that men shouldn't be allowed this as well. There's nothing wrong with physical affection no matter gender or sexuality.
EDIT: Also, on the occasions that I see wrestling, no matter what type, real or not, I see men in skimpy clothing, touching, grinding, holding, rubbing their hands and a hell of a lot more together....and yet holding hands after a victory...that crosses the line?...Really?
