I'l read those links when I have more time but my internal logic tells me that being gay or straight is not like choosing between Carls Junior and Burger King.
I never found Bob or Jack sexually enticing.I did find Sally and Gina to be a turn on.
Whats so crazy is that I got along much better with Bob and Jack.I just never wanted to go to bed with them.
What I think is important is reading what ex-gays have to say. The I Do Exist video tells the story of 5 ex-gays and is quite revealing. The ex-gays state their formerly held same-sex attractions were not a choice. They clarify their statement by saying their attractions were not a choice because they were confused about their sexuality.
When I first started reading about homosexuality I had my own biases that I thought were correct. Since then I've refined my position by doing thread things: reading, reading and reading. When you have the time I encourage you to checkout the links on this thread.
