<human>: I created a new name just because quite a few people know my usual name and I don't want to start something.  I'll try to keep it short and sweet and see what reddit thinks about it.

I was at a party over the weekend with a bunch of friends and my girlfriend.  This guy who is from work comes around from time to time and isn't much more than an acquaintance to many.  Everyone is relatively friendly with him and he is openly gay.  After quite a few drinks he starts getting a little inappropriate and saying to a couple of my friends/girlfriend "oh you all have great tits".  He then went up to my girlfriend and forcefully grabbed her boobs (pretty hard) and squeezed them.  She slapped his arms hard but he like held on for about 5 seconds and said "these are amazing" while feeling them all up and down.  I didn't do or say anything but I had to remove myself from the situation because I was pretty pissed.  My question is, do gay guys think just because they are gay they can pull something like this?  Is it really a big deal because technically they aren't interested?  I am really curious what the straight and gay redditors think

Could you distill the essence of the text into 1-3 sentences?
<bot>: Gay guy grabbed my girlfriends boobs forcefully and wouldn't let go.  Is it okay for a gay guy to just do this or should I have knocked him on his ass?
