To be honest I don't know if it is a choice, or if it is genetic. Either way there are things that are choices that are morally wrong, and things that (science says) are genetic that are morally wrong. I mean it could be (and has been) argued that (most) men are genetically inclined to mate with every young woman they see. There are scientists who say that it is genetically ingrained in men to spread their seed as far and wide as possible, like some animals in the animal kingdom. Yet if a husband does this while he is married, he will end up in divorce court. It is morally wrong for him to go cheat on his wife, despite what his genetics might tell him.

As far as that goes, what a person chooses to do, or not do is up to them. They have free will. I wouldn't choose anything for them.
