Hair patterns? Wow, would not have thought of that. I've heard of piercings too... I wouldn't consider that.
I'm indifferent about that body part. To me, acne is much grosser. I hate acne.
Vaginae are just... skin... and hair... and secretions... but we get secretions all over - sweat/oily shine... and shedding skin/hair... and then there's the nose/mouth... all just part of the body.
