A good freind of mine who happens to like a bit of bum fun, once tried to cure himself of his 'illness' when he was much younger.
He hated the fact he was into looking at blokes a great deal more than at pretty ladies, so he tried to cure himself of this awful burdon by going with a lady of the night.
He honestly thought after a bit of box action it would change him and make him into a real man.
Of course, it was all bollocks, and it obviously didn't work, in fact he couldn't even get a hard on, he just felt sick at the sight and touch of this womans body, made his excuses and moved on.
People are either genuinely into male or female sex and relationships, it's totally natural to them, they have no choice, it's what they're into.
Get over it dude and accept it......
