Sexiest Piercing?

I havent seen it,

 

LOL im sure she'd show you if you asked, she isn't shy.

 

collar bone

 

i love my kneck, got the base of my kneck pierced with a bar about a month ago and i love it, can only see it if i tie my hair up

makes me sleepy if i sit and play with it
i dont want to ruin my lucky 13 piercings bt thinking of getting tongue, hood and few more in ears
not at once just i get bored

On a bloke i like nipples pierced, like the lip idea but can look dodgy on some ppl
basically i find piercings sexy what ever
