Probably be more privileged/bigoted. Make fun of gay people and feel superior and more masculine/attractive compared to them. Have a happy life, one filled with options and without the worry of being accepted for your sexuality or worrying about if someone is gay or not.
Why do you all say 'more bigoted'? A significant amount of straight men are accepting of gays. My family is not even conservative why would I be a bigot if my orientation got changed?
Do whatever boring straights do, listen to what society tells me I "should" do, study hard for a boring job I don't like, marry a woman I don't really love (or fall out of love with, and get a divorce), have 3 kids who all grow up to hate me and spend most of my days with the boys at the bar watching the game just to get some piece of mind.
I'm probably married already. Or at least screwing our young cute housemaid. To think that I have fantasies on our basic male helpers but can't do anything since i was supposed to be straight.
