Despite the myth glossy magazines continue to perpetuate, a man whose body is as hairless as a newborn seal is not more desirable. Work with what God gave you, not against it. When you insist on shaving your chest, arms, and all of your pubes, you look like you should have a vagina, and when the stubble grows in, we feel like we're hooking up with a lazy transvestite.
Instead of trying to compete with her to be the baldest one of all, embrace your body hair. It's manly and (this just in!) masculinity is sexy. The sole exception: We don't want to undertake the impossible task of parting your pubes like they're the Red Sea to get to your penis (or worst yet, choking on them), so trimming is always appreciated.
