Being 6'5 and living in the United States 3rd or 4th largest gay population center (Seattle's capitol hill, just like castro in SF) I get my fair share of gay male attention. For the most part it doesn't bother me. A lot of them are my friends and I enjoy their company.
However every now and then a real flamer will ruin my day. There is something about their behaviour that just freakin' annoys me. Personally I don't care if a guy smokes pole or not, sexual preferences aside I find I have a lot in common with them as people regardless. But the world doesn't need any more freakshows. And the guy skipping down the straight with a "Getting Lucky in Kentucky" t- shirt screaming and grabbing random asses is a bit much. (that does happen). Of course the minute you ask them to try and behave like a normal human being you're a "homophobe". Hell, even girls I know get grossed out by it.
My advice to gay men is to do whatever you want in the bedroom, but realize that certain behaviours are just distracting and unesscessary. To be rabid about cock is unhealthy. I like pussy, but I don't dress like a girl and act like one to get it. If you guys really want dick, be the men you're attracted to. That's my theory.
