Do you know why women use eyeliner, eye shadow, or other various eye makeup? To make their eyes seem bigger. Think how cute things with big eyes are; babies, and tarsiers. Do you know why women use lip liner, lip stick, lip gloss? To make their lips seem fuller. Think lips down there, when things get heated. Why do women wear bras (push ups, etc)? To make their breasts seem bigger. Think great for breast feeding kids. Why do women like to wear tight clothing to look "sexy?" To make their bodies curvy. Think wide hips to pop out babies.
What's my point? Well, obviously, over the centuries, women have perfected ways to capture a man's attention (subconsciously). It's obvious we (men) have a hard time controlling our hormones subconsciously when it comes to a woman's physical features, and it's harder when they know how to enhance those features.
And what do men have to attract women? Sweat... yes, that's right. Sweat. More accurately called pheromones. So if you're smelling that musky man smell, run, because sooner or later, you'll be thinking of tearing his clothes off and making an army of cute babies with him.
That's why I don't shower for days... Kidding... not really... really.
