It is not weird. Men always get along with men, while woman get along with women. Gay men are like women, but like you said "minus the sex".
So guys would rather hang out with guys but have sex with woman, and the same goes with woman.
It is the sacrifices we give that give us the life we want. We can't have it all, but we can certainly try to shoot for the sky, at some point we will hit a limit, like an attractive woman finding gay men perfect even though you can't have them. :)
Best wishes to you
