I have long been frustrated by the lack of specifics in the vast majority of articles about masturbation. Even once we've moved past asinine cultural notions that masturbation is for "bad girls" rather than all women who want to do it, and we're in agreement that making yourself feel good is healthy and fun, supporters of self-love tend to dole out vague, "sex-positive" exhortations to touch yourself — and then leave you to it.This frustration led me to team up with rock star sex therapist Vanessa Marin to bring you a first-of-its-kind 30-Day Masturbation Challenge. We're about to show you in gorgeous, anatomically correct GIF format what to do when it's time to love yourself up — and to see if you can do it every day for 30 days. (This is going to be the best New Year's resolution you ever make.)
