Gay guys have more casual sex than straight guys. Read an article on that yonks ago. There are statistic around to prove it (I'm not Googling that whilst logged in to my Google profile!).
And it makes sense given what we know about the differences between male attitudes to sex and female attitudes, once generalised across the whole population.
No men want more casual sex.
The differnce with gay men is the other half of that equation is another man not a woman who typically doesnt want casual sex.
Gay men are no more sexually aggessive than straight men, its just there is no woman to act as a brake on the situation.
To say a man in a gay bar is fair game is identical to saying a woman in a straight bar is fair game.
And its a pretty gross statement either way. Seriously though if you'e ever on the receiving end of sexual aggession from a bigger stronger man it' almost a certainty you won' act like your saying women should.
But as you say its a male attribute it comes from.the sexually aggressive male to whoever they'e targeting male or female, jist odds are a gay guy will be more into it than a woman.
