The best argument for nature that I have heard is that because more then just humans exhibit homosexuality at a some what stable rate of the believed 8-10%, it is a natural population growth curve to prevent the over consumption of natural resources by cutting the amount of any species that actively engage in reproduction.

Obviously no proof for any theory but this one made the most sense of any I have heard. Though being possessed by demons is also a cool prospect.

Well I find it hard to believe that being gay could possibly exsist in the genetic code purely because it makes it far less likely that your going to have offspring and therefore pass on your genetic code if you are and therefore it would've died out. Which makes me want to say that its entirely nurture. However having several homosexual friends they all think that it wasnt a choice that they made and their upbringings vary wildy.

Theory says all nurture, practise says all nature. I'm going to say its neither and actually being gay is decided entirely by whether or not you like peanuts.

Sexuality is genetic and cannot be changed as such. However, whether a person will "discover" their sexuality and/or act according to it, is another matter entirely. Socialization processes, cultural norms, religious beliefs and life experiences (to name some aspects) will affect how you percieve your own sexuality and how you incorporate it into your personality. In preactice, this means that people can sort of "choose" their sexuality.

In the end, none but yourself can truly know what goes on in your mind. It is all too easy to judge other people's perceptions of reality. Belief is a powerful force that can alter the seemingly unalterable, and a person "choosing" to deny his/her sexuality doesn't neccessarily live a miserable life in denial. A person who doesn't share your concept of sexuality may still be perfectly comfortable with the life s/he is living. One might say that this is because s/he doesn't know any better, but then who does? Your reality is not everyone's.

That rant took a slight turn down Philosophical Avenue. My point is that sexuality is genetic, but how we act upon it is up to each individual, and the way we act is not neccessarily unnatural even though we act against our "true" sexuality.

Sexual orientation is mostly due to genetics, epigenetics, and prenatal development, I reckon. People who say non-straight sexual orientations aren't "natural" simply don't know all that much about biology.

Both, but usually nature. I would say genetics only, but I also don't think there's much of a limit to how a person's upbringing, good or bad, can shape who they become.
That pretty much sums up my opinion. Though something that causes a change in sexual orientation would probably have to occur during very early childhood.

I say it's nuture.

The idea of homosexuality being something "in the genes" never caught on with me.

This is a common argument against nature's influence. No one knows if it is genetic - either as a single gene or multiple gene interactions, or if there is an in utero event.

However, if it is genetic, then it could be a recessive gene which would not simply die out.

No, nonononono. That's not how it works at all. There are several ways that would enable a genetic component existing in homosexuality.

First of all, there's heterozygote advantage. It could very well be that homosexuality is a pure form of a trait that is advantageous in a "diluted" form. And wouldn't you know it -- according to some studies, the siblings of homosexuals appear particularly reproductive. There are other traits that behave like this.

It could also be that it's a trait that has no particular effects when it's recessive and not expressed. If it has piggybacked its way on an advantageous trait that has been selected for, it doesn't matter if non-reproductive offspring is born once in a while because the reproductive carriers make up for them.

Now, add kin selection. You don't have to be the one to create viable offspring in order to pass your genes on, y'know. Your siblings and cousins are made of the same stuff as you and nature doesn't call you out for cheating if you instead help your siblings hook up and ensure that their kids do better than other people's kids.

Also, it's not like your DNA is the only non-choice factor. Prenatal development and epigenetics play a huge role in our lives.

I say mostly nature but there are probably times when it's been other factors. For example a childhood friend of mine was bisexual with a preference for men, but when almost every boyfriend she had abused her and basically treated her like crap she said fuck it I'm sticking with women. Now she says she doesn't really find men attractive any more and considers herself purely lesbian.

But my vote is that it's mostly genetic. That's why I hate it when gay people say "When I became gay" or "I turned gay when I was [X] years old". You guys aren't helping! Dx

There's a lot of evidence pointing towards the influence of prenatal hormones in male homosexuality, but female homosexuality is less well-understood. So environmental factors: probably, but upbringing: probably not.
This is what I've been told, although, I only went to one extended seminar in university on the subject so I'm in no position to make assertions about it.

My opinion is that it's nature for both but the female homosexuality statistics are a little strange compared to those of homosexual men.

It's a mixed bag I think. Genes might predisposition someone for a specific sexuality, but I think experiences during formative years is a big factor as well. I've only got anecdotal evidence; A guy with a choking fetish got choked by an abusive babysitter. A pedophile was molested as a child. A "slut" had obvious daddy issues. Nothing conclusive, but it seems to indicate that "nurture" plays a big part...

I think the environment in which one is raised has a far greater impact on sexuality than genes. Obviously none of us know for sure, but I'm a little surprised how many people have gone for nature.

Nature, you can't be forced to be gay if the straight, the same way lots of gay people are forced to be straight. You either are, or your not (or bi-sexual but lets not get into all that)
I'm bi :>

Yeah, I'm going with nature on this one. Nurture might have an influence, but from my experience and sources it looks pretty nature.

I truly think it can be one or the other...or even both. Life is way to complex for such things to have a single right answer.

What tends to be found in the nature/nurture argument is the reality is found somewhere in the middle. I'd say genes play a major factor in it, but how someone is raised can definitely affect how they see themselves and how they accept who they are.

I do believe it's as much nurture as it is nature. I have seen what an impact different kinds of parenting can have on kids that are geneticly identical, so I do not believe nature is the only factor, nor do I believe it is the major one.

I think that while people may have a predisposition towards a certain sexuality, it still boils down to the actual decisions made by that person or made by those who raised them. For example, there have been genes associated with alcoholism, but in order to be an alcoholic, you do have to pick up and drink from the bottle. You may never know until you try drinking. I've had a couple friends who were completely happy with their sex lives before they ended up, one way or another, in a same-sex sexual situation. After those situations, they decided they were either gay or bi, but beforehand, they hadn't considered that possibility. So, in my opinion, while some people may be genetically more likely to be homosexual, there is a nurture aspect to it that I feel is more important.

So I guess the obvious question is: can your [sexual] orientation be influenced by outside..um things, or are you just born that way?
Here's the deal:

When people talk about homosexuality they are generally talking about one of two things.

Liberals, hippies, human sexuality experts, professionals from the psychiatric sector and human rights guys from Geneva or Hague are talking about sexual orientation which is about what you want, id est, the sex of the partner (or partners) that will most fulfill you sexually.

The sexual orientation of humans falls into three categorys. They're either heterosexual (attracted to the opposite sex), homosexual (attracted to their own sex) or bisexual (attracted to both sexes), and this is determined usually by a number of natural factors, including genetic predispositions and number of older siblings.[footnote]The more elder brothers (surviving or not), the more likely a son will be gay. I don't know what the stats are regarding daughters, or sons had after daughters.[/footnote]

Regarding bisexuals, their own orientation can vary from mostly prefers men to mostly prefers women, and can change over time (and generally does). There's a lot of conjecture amongst human sexuality experts that a lot more people are bisexual than we let on.[footnote]Bisexuals get hate from both sides of the fence, so they have much reason to hide. Homophobic communities treat known bis as gays who steal from the straights, and gay communities regard them as traitors to the cause. Both sides presume that bis are indecisive sluts who are incapable of being monogamous. None of this is fair or necessarily true, of course.[/footnote]

Conservatives, Christian fundamentalists, The Roman Catholic Church,[footnote]This has actually changed since the new papacy when it comes to the priesthood. The Vatican has now excluded from the seminary male students who are naturally attracted to other men. This wasn't regarded in the past, since priests take a vow of celebacy anyway, but now they have to be specifically resisting temptation of female flesh. Go figure.[/footnote]reparative therapy [http://en.wikipedia.org/wiki/Reparative_therapy] advocates and various other pro-normativity groups, when they speak of homosexuality, are regarding only behavior. To them, it doesn't matter if someone has a sexual preference for their own gender, so long as they are not actually having gay sex, they are not gay.[footnote]These groups also assume that if you have gay sex once that you are gay until cured or exorcised or something. The queen for a day rule that applied during DADT may apply depending on the society. Generally, it's a good idea to not get caught.[/footnote] It is this way that they can have statistical success with reparative therapy, so long as their patients don't relapse.

As behavior, homosexuality is a matter of nature and nurture. Someone can be outright gay, yet pressured not to act on it, and thus abstains from sex entirely. He'd be counted as straight until proven otherwise. A woman who is bisexual but, due to societal pressures, is only actively sexual with men would count as heterosexual until she was caught with another woman. The intrinsic desires along with the psychological well being of the individual are not considered since humans are a depraved sinful lot, and but for our savior Jesus Christ, fallen from God's grace.

Likewise, someone thought to be straight can be affected by a corrupting influence (say, a community in which acting on gay desires is permitted and even welcomed) and that would be seen as having been turned gay via an element of nurture. If a successfully treated lesbian was persuaded via reparative therapy to give up her sinful ways, and then was courted tempted by a like-minded cutie minion of Satan sent straight from the charnel depths of Hell, it would be evident she was corrupted back to her evil ways by an outside force of darkness, i.e. again by nurture.

This latter scenario, it turns out, is fairly common, as folks with inhibited homosexual desires often will seek out a less constraining community in which they can express their sexuality fully, rather than stay miserable in the society in which they were raised, even if doing so means exile from their family.

I think it's a mix of both really.

Don't think genetics governs who you are, but, it can certainly affect you.
Agreed with this comment.

I think some people are genetically more inclined to certain types of sexuality, but certain personalities are more inclined to embrace that side of them. I'm no expert, but that's my ideas.
