>>736143I don't know, but you can start with the les intense things: mutual jerking, frottage, blowjobs, I asume threesomes, bisexual porn?. You don't even need to get into anal sex, there are gays who don't do anal.
I don't really know if it works since I am naturally gay.
For the romantic side maybe you could search about that techniques political lesbians used/use to develop their (I assume pseudo-)homosexuality.
Many gay guys have a thing for straight guys so maybe you could take advantage of that.
