One of the worst things I hate about gay life is the bullshit they do like what you described. For some twisted reason gays think it's ok to walk up to another gay, stranger or not, and start grabbing nipples, asses, etc. I detest it and have made scenes to show that I do. One drunken idiot kept doing it to me at a bar and I asked him to stop it. One night when I walked in he was about to do it and I grabbed the shit out of his skin and I twisted it for all it was worth and he complained that it hurt. He never did it again. I am bi, and in the straight world it is not acceptable to walk up to a woman and grab her tits or her ass, so why should it be any different with gays? There are many things in the gay world that are just flat out repulsive.
