So this is going to probably piss some people off but the best way I can describe it is because gay men are basically women with dicks.
By that I mean they are men, yet some behave and have the same sort of interests as a ton of women. So you get the ability to have a friendship with someone who has the same interests, behaviors, and taste as you but they can maintain friendships like a guy. Its this strange blend.
Thats probably confusing and not a great way to put it, but its the best Ive got right now.
