How to explain homosexuality? Options

[Call911Quick]

OK, so as not to step on any toes, let's assume evolution is how the world came about.

Now, homosexuality goes against every theory of evolution that has been thought up. There are certain lizards somewhere that are all female, but they don't have sex. They lay unfertilized eggs, so essentially they clone themselves.

We're studying how and why sex and sexual reproduction developed and everything. So, obviously, homosexuality isn't "programmed" into us.

So what makes a guy gay? Is it increased levels of estrogen? Decreased levels of testosterone? Is it psychological/self-induced, or can you not help it?

I don't understand how any guy can be gay. Lesbians turn me on, but I mean... Ever take a REALLY big shit? Imagine that, but backwards. And continuous. I mean... it's like watching two porcupines have sex. Wait, that's a bad metaphor, more like... watching gorillas have sex.

...

watching gorillas have sex.

That makes me think of the end of Ace Ventura..the second one I believe and how the gorilla grabs the guy and starts banging him.. ( watched it last night o_O)

Anyway..Personally I think its all psychological and self induced. I just can't see how someone is born gay and I will never believe that. I think people turn gay or attracted to the same sex through their experiences in life. For instance if a chick was raped when she was a child or mis treated by a man then it could make her unattracted to men which would leave her to attracted to women.
