I remember a post by Xiphoid on this subject, Mickaelia. It’s been around for a while, so you’re not the first to notice. The difference is in our motivations, why we came here in the first place, and I’ve quoted from my reply to her in that thread.
More sex is a powerful motivation for men. Couple that with the problem-solving, rational, engineer-like mentality that many men have, trying to come up with the perfect sex potion, and you’ve got a potent combination.
