LOL. ;D Love the picture. Gawd, monkeys are vile beasts.
It's the whole meterosexual revolution - I call it caring about your appearance, and looking good. It doesn't mean that you have to dress like a fruitcake, but buy nice clothes and keep them proper for going out in the town. It feels good when you look good. And if you shave down there, your partner will probably like it too.
