Homosexuality: Condition or Choice?

In this modern day and age, the idea of homosexuality is not uncommon. Debates rage truculently over whether being gay/lesbian is an actual condition or a matter of choice. That is, if a person is arbitrarily determined to be intrinsically gay/lesbian by birth, or if a person decides to turn gay/lesbian based on individual preference and as a result of his nurturing environment. I have to say that I strongly advocate that being a gay/lesbian is an actual condition - and not a matter of choice for most gays/lesbians. I believe that if they could make a deliberate choice, that they would choose to be straight for in many cases, being gay/lesbian is simply not worth the trouble, ostracizing, and pariah status. It even gets violent many a time. In addition, scientific research has pointed to biologically empirical evidence that the gay condition may likely to be caused by a hormone effect in the first sixteen weeks of pregnancy. I have a friend who confided me a few days back. He 'came out' but only to me and another friend. My initial response was one of shock. He was a buff, masculine and just not a stereotypical gay man as we normally perceive. Of course i asked WHY!? and he just responded. " I don't know why... I just am sexually attracted to Men.. I really don't know why... I suppose I was born like this". I know for one that if he had the power of choice that he would definitely choose to be straight. This, he said in his own words. But somehow, something inside of him, some unknown abstract force, wills him to be and do otherwise. This only served to corroborate my initially held view that it is a matter of condition vis-a-vis choice for them. Hopefully I get to hear from a gay/lesbian as one of the response(s). I truly am intrigued by this subject and the possible permutations of answers that are out there.
