MYTH
“Normal” women reach orgasm through intercourse.
FACT
Only about a third of women experience orgasm regularly during intercourse. Another third can reach orgasm with intercourse with extra stimulation. A final third never achieve orgasm during intercourse but can by manual and oral stimulation. Having orgasms by means other than intercourse is a normal variation of female sexuality. In the past, people thought that “mature” women had their orgasms with intercourse; you will sometimes run across an older book that has this view. However, laboratory studies in the 1960’s showed that an orgasm is an orgasm no matter which way you obtain it. How a woman reaches an orgasm has nothing to do with her mental health or emotional maturity.
