Absolutely none. I find it to be a Tramp Stamp. What are those girls going to look like after they are over 50?
I have gone on for about 15+ mins without noticing a nose piercing...it was very small and I didn't get the point of it. Or the Dennis Rodman customization where he cut the head of his penis down the middle supposedly to increase sensation during sex...OUCH.
Dogs are weird in mating. Stuff you don't want to think about. Never personally seen house cats do it but the foreplay is wicked. We have nothing on the animal world w/ our piercings & brutal visions of great sex. Any cat, dog or lizard can show you how it is really done no gentle foreplay, the pinning of mate to the ground, no backing out until the deal is done. Everyone leave with scars.
