Are you aware of the twin studies(Identical twins)? Pretty much determines that who you are is based upon how your mom and Dad's DNA combined. You know, wheether your tale or short, smart or dumb etc. Based upon my research my estimate is that Genes determines who you are 70%, and culture 30%. Another factor that impacts things is the use of alcohol and drugs by the parents.

Your sexual fetish and behavior is not determined by DNA in any way shape or form.

I stumbled across some show once, accidently, and watched a host of a TV show berate and badger a man trying to TELL him he had to be gay because his twin brother was.

It was disgusting.

Googling around there don’t seem to be too many studies of homosexuality in twins. One seems to have found a roughly 50% matching rate among twins who were raised together. The methodology in that study seems to have been questioned a lot. But 50% in twins raised together seems to show there isn’t a strong genetic cause, since physically these are identical twins. And unless the twins were separated, we can’t know if they were exposed to an environment that led them both into this lifestyle. Certainly if your twin sibling starts doing something of his own accord, you might be inclined to imitate him, whether it be drinking, drugs or this.
