Apparently you didn't look very hard: http://www.theguardian.com/science/2014/feb/14/genes-influence-male-sexual-orientation-study.
It appears that homosexuality -- as is the same for so many other psychological constructs -- arises from a confluence of environmental factors and genetic ones (i.e. diathesis-stress model). In layman's terms, what this means is that certain people are more prone to homosexuality because they are genetically predisposed to it, but that homosexual behavior will not arise until certain environmental factors are present to trigger that behavior (e.g. a person or group of people who regularly and openly engage in homosexual behavior). Beyond that, there is most likely a third element or factor which could simply be called choice: a person, given the desire and opportunity to engage in homosexual behavior could either choose to do so, or choose not to. The issue is that if a person does feel strong desires to engage in homosexual behavior, them choosing to deny their impulses to act on those desires may lead to harmful long term psychological issues of sexual repression.
People who try to boil homosexuality down to some sort of moral decision are simply ignoring the scientific facts -- not to mention the essentials of a truer morality which grants human beings the freedom to choose their sexual identity. Encouraging individuals to flat out deny their sexual impulses is psychologically destructive. Homosexuality is as natural as any other behavior in modern human society. To say otherwise is contrary to science and to ethics.
I read the whole article and I have to say, I stand corrected. The genes play the mere role of 'tendency' of a person to be a gay or not. After that, it's up to the environment and other factors. It's just like, there's a tendency to steal, to murder in every human, and after that, it's up to the human and his upbringing. This part explains it even better:
The gene or genes in the Xq28 region that influence sexual orientation have a limited and variable impact. Not all of the gay men in Bailey's study inherited the same Xq28 region. The genes were neither sufficient, nor necessary, to make any of the men gay.
The flawed thinking behind a genetic test for sexual orientation is clear from studies of twins, which show that the identical twin of a gay man, who carries an exact replica of his brother's DNA, is more likely to be straight than gay. That means even a perfect genetic test that picked up every gene linked to sexual orientation would still be less effective than flipping a coin.
And thus the conclusion; it's not natural. What's natural? How will you define natural? something that exists? or something that's made to exist? Of course, the former here is what we mean by natural. If you say, something that exists is natural, then tell me, are cars natural?
After reading that whole article, it has led me more towards the concept that this is rather an unnatural behavior. Ok, let's posit, it is natural. By your definition only. Now, why is there a greater risk of AIDs and STDs involved in homosexual behavior? skip the question. If there is this risk, then doesn't it make more sense to prevent this kind of behavior?
