50 Cent has turned sex adviser on Twitter.com in an effort to help lusty male fans quit pleasuring themselves. The rapper and entrepreneur labelled masturbation "a sin" in one recent tweet, and he has now addressed all the feedback he has had from fans asking him how to avoid solo sex. In a bizarre series of posts on his Twitter blog, 50 offered up a step-by-step guide to stop the guilty pleasure. The "Magic Stick" hitmaker's pointers include: "stop going to porn sites," "Make a conscious decision not to turn your head after people walk by you," and "Do not go to strip clubs." 50 also suggests single men who struggle to give up masturbating should work-out whenever they feel the urge.
