I believe that much of homosexuality is explained in this study review:
http://www.ncbi.nlm.nih.gov/pubmed/22364652
If an individual has full capability to use either hemisphere of the brain, which putting it simply is more effeminate or masculine in thought and emotional tendency. Exposure to the "right" family social conditions a male for example, could find himself more or better adapted to what is the effeminate, 'right thought process'. For a female the opposite occurs, where she becomes acclimated to the 'left thought process'.
This is not the formula for what many religious organizations claim to be a sin.
Can being gay be a choice?
I think so, anyone can only have an intimate relationship with the same sex, but to exhibit and live by the traits of the opposite sex, would be a tough act to carry on for very long.
lol that reading piece was very wordy... looked like someone went through with a thesaurus and changed everything they could
