In fact, according to a 2017 study published in the Journal of Sex and Marital Therapy, 37 percent of American women required clitoral stimulation to experience an orgasm, and only 18 percent (!) of women said they were able to come on vaginal penetration alone. In reality, surveys say only about 57 percent of us are climaxing every time we have sex, and that’s usually when a form of stimulation other than penetration is involved. Orgasms for folks with vulvas aren’t an easy get through penetration alone, nor are they so elusive and complicated that they aren’t worth trying for. First thing to know: don’t believe all the hype and myths from movies, porn, and TV.
