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.

An aversion to homosexuality, or the belief that it isn't "natural" isn't programmed into us either.

If you think about it, the very concept of was IS natural is essentially socialized.

But let's keep running with evolution.

Assume males have slowly begun to evolve into homosexual beings.
Assume males have now turned completely into homosexual beings.
Assume now that the reproductive organs of males has changed.
Assume now that the reproductive change allows males to reproduce.

Evolution, is endless.
