Researchers interviewed 4160 Norwegians aged between 18 and 89. 66% of women and 84% of men reported masturbating in the past month. Most women said they do it two or three times a month. At the same time, most men reported masturbating two or three times a week.
They also found that women with a higher frequency of sexual intercourse were more likely to report a higher frequency of masturbation and higher sexual satisfaction. So for women, this application usually performs an additional function rather than a substitute function.
But among men, frequent viewing of pornography was associated with sexual dissatisfaction. That is, their masturbation serves a compensatory function.
