environment as I can't believe that someone would be born gay or lesbian. Some guys were married, having even kids and then will leave everything behind to become gays ... 

Please don't tell me that this is natural or got nothing wrong with it ... just one example that shows it is not natural in most [if not all]  of the cases ...

One more thing, how can a woman reach that level in her relation with a guy without realizing that he is a gay? Just a thought ....
