'True Blood' serves up a lot of blood. And sex. And bloody sex. And if you happen to enjoy these things, it's likely you're tuning in to HBO's mega-hit Southern vampire saga every Sunday night for a fix. But this season -- the dirtiest yet! -- has us asking, has it gone too far?

In the same pushing-the-undead-envelope spirit, the stars of the show "grace" the cover of this month's Rolling Stone, and the bloody, flesh-baring image has everyone talking.

Rolling Stone interviewed show creator Alan Ball for cover story 'The Joy of Vampire Sex,' and he takes a few jabs at a certain popular rival vampire phenom, the 'Twilight' saga. "The idea of celibate vampires is ridiculous," Ball says. "To me, vampires are sex. I don't get a vampire story about abstinence. I'm 53. I don't care about high school students. I find them irritating and uninformed."

Bigger and bloodier after the jump.
