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.

n*gga that shits gay

any addition to this topic?

After reading all of the replys, it is interesting. I can only speculate as to why it is.

No I don't believe it has anything to do at all with evolution. We are "turning" gay because of evolution. I believe it is because of how you were raised and how you reacted personally with your environment. In other words in regards with psychology. Also, I am open to how you may have different reactions of chemicals in your brain.

sorry I meant that not because of evoultion
