Naah, I prefer them natural and naked. Don't like to see bits of metal passing through flesh - I'm squeamish like that. Unpierced is infinately more sexy.
They look OK, but my girlfriend has two piercings in her bellybutton and they constantly snag onto my clothing when we're hugging. There's nothing that breaks a loving moment than the words.. "Oh, f*ck, I'm caught again"....
not a fan of any piercings myself - the body is beautiful enough on its own....took me til I was 26 to get my ears peirced!! some piercings are downright un hygenic - noses etc.... GROSS!!
It's a style that has been taken on by all women - whether they are foxes OR dogs. It therefore leaves me a bit cold. Naked belly buttons are best. As are unpierced nipples, and unpierced tongues.
For years I threatened to have my navel pierced. Nowadays I'm glad I didn't. Not least because ancient old birds should keep their stomachs well covered by their vests. No matter how flat the ancient stomach is!
