After countless sex scenes on True Blood, Ryan Kwanten knows a thing or two about getting intimate. The HBO actor, 33, is writing a sex guide, The G-Strategy, and his pals are already taking his advice."I gave it to a couple of my friends and they’ve got back to me sort of a week or two later, saying, 'Oh my God, Ryan! Where did you get it?'" he tells Access Hollywood. "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." He describes his audience as, "Predominantly with men, it's more the finance-type world. With those, you've got the Wall Street guys that lap up anything that's a chance to make a quick buck."
