?? For once I think CrAz3D is making a reasonable point and I'm confused why you're arguing with him, when you seemingly agree.
I think sex is enjoyable, but when you think about it objectively it is weird.
I don't think equating oral sex to "licking a urinal" is apt. Calling it 'weird' is.. well, weird. I mean, there's nothing more natural than eating, drinking, excreting, and mating. The enhancement and enjoyment of any of those (whether it's cooking food, creating toilet paper, or using different orifices) is an extension to our most natural needs/desires.
