[[I'm not sure if I'm allowed to post URL's on this site but since I always learned to verify the source of my information I'll just do so. Tell me if I'm doing anything wrong. Thanks.]]
First I would like to say that I've not read all articles in the links I've disclosed in this reply since it's not worth it. I just want to show that I'm not that uneducated. Off course the omnicient knows more than I do, but saying I'm entirely ignorant is untrue.
Also I would like to say that there's a chance that I'm wrong. But since it's a discussion, and I do believe Homosecuality isn't a choice I did take some time to look for some sources sharing my point of view. Normally I know better than to argue with someone like you, since there's no use, but everyone commits sins in time.

Is sexual orientation a choice?
No. For most people, sexual orientation emerges in early adolescence without any prior sexual experience....
http://psychology.ucdavis.edu/rainbow/html/facts_changing.html
In many of these behavior-change techniques, "success" has been defined as suppression of homoerotic response or mere display of physiological ability to engage in heterosexual intercourse. Neither outcome is the same as adopting the complex set of attractions and feelings that constitute sexual orientation.
Wikipedia isn't a reliable source, but still I want to mention what it says here:
http://en.wikipedia.org/wiki/Choice_and_sexual_orientation
Today, most mental health experts agree that sexual orientation is not chosen. Numerous surveys and considerable anecdotal evidence shows that the gender(s) toward which most people have had spontaneous attraction to (whether heterosexual, homosexual, both, or otherwise) have not changed since the feelings began in adolescence or beforehand.

Is Sexual Orientation a Choice?
No,
Can some gay men and lesbians change their sexual orientation? 200 participants reporting a change from homosexual to heterosexual orientation (1). By Robert L. Spitzer says:
An increasing number of clinicians believe that such change rarely, if ever, occurs and that psychotherapy with this goal often is harmful by increasing self-loathing, lowered self-esteem, hopelessness, and depression.
Off course there are also some sources who say the opposite:

Is it changeable?
Yes, through counseling and prayer. But it requires effort because it is so addictive.
and I have to say also some reliable sources like this one:

If any thing in my post came off as offensife I apologise. Also I'd like to apologise for any spelling/grammar/interpuntion errors I made in this post. English isn't my native tongue.
