It's unnatural.
Actually, animals don't make a distinction between female and male when it comes to trying to reproduct. If there's anything natural in the world, it's animals.

as i said on the other thread, the only people who seem to have no respect for other people are the anti-religious people!
How?! Nobody here said something insulting, merely disagreeing. If that is disrespectful, I would find it very disrespectful as well that religious people would disagree with my disbelief.
I don't see why it has to be such a taboo, perhaps it's insecurity among the believers...?
