According to Kinsey, maximum masturbation rates were to be found in children under the age of fifteen. For this age group the maximum frequency of masturbation was in excess of twenty-three times a week.

Some females surveyed had experienced orgasm from this source as many as thirty or more times in a week. Some energetic females had masturbated to orgasm as many as one hundered times in a single hour! But some women only tried it once a month.

Kinsey concluded that "the range of variation in almost every type of sexual activity seems to be far greater among females."
