I don't find nipple piercings attractive on men or women. To me they are a turn off and seeing them makes me get sympathy pains. Nipples are beautiful the way the are. Well, most of them are anyway. As for doing it for pleasure, well they work very well in their natural state. They seem to be perfectly designed for nursing babies and for grown up pleasure. To each his own and live and let live; but hey, the other parts work very well in their natural state as well. I think if they worked any better it might just.... well, I won't go there. Nature has done a splendid job at least for me. I'm happy the way I am and I like men with good old natural stuff, too.

PS: Stacy, I had been wondering what would happen if women posted avitars with their nipples, bejeweled or not here on JWD. I kinda think they'd be edited out.
