Well Joe says NO, but don't they all...

Reports have been circulating that Joe,  who once wore a purity ring claiming his virginity -- filmed himself doing dirty nasty stuff with his girlfriend Blanda Eggenschwiler while they were drunk and high!! The reports claim the sex footage features some crazy BDSM stuff, including paddles and ball  gags.

But Joe's rep tells TMZ, it's total BS ... no such tape exists.
