No it isn't. Gay/bi men have sex with men.
don't tell me you're one those stupid people that can't separate fiction from real life.
You realized that no penetration happens in movies right? Hell, most of the nudity is stand ins or CGI.
I hope you are trolling, being homosexual isnt just about penetrative sex.
Homosexuality is the attraction to the same sex, a lot of gay men never have sex with another man, they live a life of lies with a wife and kids.
You seem to be mixing things up not me
