i agree with IMI... I circle around with loads of gays frens... both gals and guys.. not that i m one of them and siding them just happen they are my frens...... but after listening to their sideof the story.... it is true that its their own desire and choice... and nothing to do with or how they are brought up.... for an example... a guy fren of mine is brought up in strict catholic family with loads of faith, believe, prayers and the right way of bringing up as normal family... but still in the enddddddddddd..... he found that he is not attracted the the opposite sex at all so... i think it pretty much is internal..... cheers.
