Many gay men love the fantasy of turning a straight guy. But generally they are too busy frolicking in the free-sex world of gaydom to waste too much time pining for a breeder.
My brother is gay. I am going to his gay wedding this year, where I may or may not meet my real father for only the second time ( I am adopted). My (real, we met when i was 20) brother, by chance, has the same first name as me. This is partly how I picked up my waitress gf. The line 'Hello, my name is Dan, this is my brother Dan' always blows peoples minds.
