Jersey Shore's self-described "guido" Paul "Pauly D" Delvecchio isn't shy about showing off -- after all, after just two episodes of the MTV reality series, he and a housemate hit the sheets, after which she announced that his manhood is pierced.

"I wasn't expecting that it was being filmed," Pauly D told E! Online's Mark Malkin. "But I don't mind. I mean, it's whatever."

"I didn't tell anyone about my piercing," he added, "but I'm not shy."

Now Delvecchio tells Malkin he wouldn't mind showing more in the pages of Playgirl ... but unlike Levi Johnston, he'd go full-frontal.
