Sexuality - Nature or Nurture

Do you think your sexuality, whether you are gay, straight or bisexual is down to nature i.e genetics and composition, or nurture, how you were raised and life factors that effect you?

According to scientists its written in your genes...

I think both play into it in different ways. Your genetics are part of it. The amount of testosterone in your body can completely effect your sexual preferences. But I know that abuse from the opposite sex can have the same effect. But I don't believe homosexuality is a choice.

Recent studies (Ivanka Savic and Per Lindström, 2008) seem to suggest that sexuality is a predominantly genetic trait. PET and MRI scans have shown similarities between the brain structures of homosexual men and heterosexual women and between those of heterosexual men and homosexual women.

Link.

However, some think that, while homosexuality might be related to the presence of a certain genetic string, such genes may or may not be activated by environmental factors. It's still a debated issue.

When you'r right you'r right.
Btw: Homosexuality is rather widespread within mammals

Many gay/lb people are denyin the existence a this gene but they still argue that your born gay? I can see their point, their scared that, one day, it il be possible ae wipe us out by elimiatin the gay gene. Can you imagine how borin the world would be.

Nope, what they are afraid is that homophobes will use genetics to try and support their idiotic conviction that homosexuality is a condition, a pathology. I can't quite see why anyone other than religious zealots would want to eliminate those genetic strings that might be behind homosexual behaviour. Besides, alternative splicing makes it so that those particular genes involved might also code for a different set of necessary yet totally unrelated proteins. There is no telling what consequences their elimination might have, which is why taking such a risk to simply try and eliminate as dangerous a trait as being left-handed would be quite stupid.

True. But, certain cultures where homsexuality is seen as disgustin, might be tempted ae destroy the gene at birth, an stuff the consequences for the person's health...

I think its down to what u prefer ... .... i dont think it has anything to do with the way u were raised or life factors

Another risc of it being only genetic or made more probably by genetics is that if one can one day test it during pregnancy, the parents will have the possibility to chose and (one day even farer away) to manipulate the genetics. Like in that Gatega (?) SF-movie mentioning a 12-finger piano player.
And some people could and would see it as a proof that everything else than heterosexuality is a genetic desease, given that both parents don't have the genetic proposition for it.

And since I'm bi I can always imaging that I am one because of my esthetic sense and the deeper understanding of loving a character and not a little percentage of one's body.^^ How good that there seem to be no researchs for the reasons to be bi, so I cn have my own illusions/explanations and no one can argue against it with a scientific thesis^^.
