Do you guys, girls too, have hair in your bums or is it strange to have hair in your bum?
Hair is part of your defence mechanism, it grows on important areas so it's an early warning if something is about to hit your head for example, that's why it grows where your brain is and your reproductive areas and on men's chest, women have a bit more padding on the chest so don't need hair, these are all important areas to be protected from impact or collision, thus you often see a bald man with a cut head, there's no hair to sense that low door frame for example, so for some reason your body seems to think your bum is a vital organ! is farting important to you?
