Prof. Kontula found that in 2015, only 6 percent of women said that they always had an orgasm during penile-vaginal intercourse, 40 percent said they had an orgasm nearly always, 16 percent of women had an orgasm half the time, and 38 percent had one infrequently. A total of 14 percent of women under the age of 35 had never had an orgasm from intercourse. (Yella Hewings-Martin)
