AUSSIE hunk and vampire Ryan Kwanten is to release a sex book

True Blood star Ryan Kwanten, 33, is putting his considerable sexy screen time experience to work in an educational tome called The G-String, Us magazine reported.

Kwanten’s friends are reportedly already reviewing manuscript details and trying out his advice, and they want more.

Explaining that he’d loaned out the book to friends, Kwanten told Us, "I didn't tell them that I wrote it, and they got back to me a week or two later saying, 'Oh my God! This is really helping me out.'

"One of my friends said his sex life has never been better! They've just taken it as gospel."

The actor, who played Vinnie Patterson in Home and Away, said he’s not sure how tongue-in-cheek the finished product will be.

"I still don't know whether we're going to pitch it as a satire ... or as a real self-help book," he said.

The book should be completed by September and is expected to be released sometime next year, Kwanten added.
