True Blood stars pose naked for Rolling Stone
The True Blood stars are shown in the buff, dripping with fake blood.
The trio are promoting the third series of the popular TV show and are happy to talk about the symbolism - and appeal - of vampire sex.
'If we go from a base level, vampires create a hole in the neck where there wasn't one before. It's a de-virginization - breaking the hymen, creating blood and then drinking the virginal blood,' Stephen explains.
'And there's something sharp, the fang, which is probing and penetrating and moving into it. So that's pretty sexy. I think that makes vampires attractive.'
Stephen, 40, who stars as vampire Bill Compton and Anna Paquin, 28, who plays Sookie Stackhouse, have been an item off screen since February 2009.
Stripping off for erotic scenes is no problem for them.
'To me, vampires are sex,' True Blood creator Alan Ball says, 'I don't get a vampire story about abstinence.'
