are gay people more attracted to straight men?

Yes

Are straight men attracted to lesbians more, becuaase they can't have them?

No. It's a ridiculous premise.

I am attracted to men. Chances are I will be attracted to more straight than gay men because there are more of them. Will I pursue them if I find out if they are straight?

Of course not - why bother.

Admittedly a very small percentage of gay guys like the conquest BUT so do a small percentage of straight men with lesbians.

no difference.

Maybe.

For me, it's just that the straight men I fall for are pretty much anything I'd want in a partner, except they're straight. I'm attracted to masculinity, and all of the straight guys I fall for are masculine.

I'm not, to be honest. Obviously there are a few exceptions, but in general I'm attracted to someone who would/could find me attractive as well. If that makes any sense

I'm not. If he's straight, I don't want to be bothered with it. I could go for a man who spends most of his time with women- not because he likes women, just for that added factor that will keep most of my time free.
