Humans faults and evolutionary biology

For the record, I'm a theistic evolutionist. I don't know.If god doesn't want us to masturbate, then why are we so damn horny all the time?Maybe god didn't make us like this, maybe the devil did it, maybe... whatever. But who knows? We don't really have much to go on with this one. There's whole debates on that one; god being all powerful and all knowing, but allowing evil...Again, I don't know. I lean towards god being something very close to, but not logically exactly, all powerful, at least not how we understand it.At least, it's the easiest way to wiggle out of the logical contradictions! They're good questions, but nobody has the answer to them.I think a lot of the questions like this boil down to not knowing why god relies on us having faith in him rather than just showing himself to us. If he showed himself to us, then we would know that he exists... but apparently he doesn't want it that way. He wants us to not know and instead have to rely on faith in his existence.There was a thread on that here: Why is Faith so Important to God?I didn't get much out of it though, and the question remains unanswered for me.
