I hope this is the right spot for this. I was thinking to myself, without the influence of porn what is normal behaviour? So I started looking up other primates and for a comparison and found this article which states that yes primates masturbate but rarely to orgasm... “But nevertheless by all available accounts, and by contrast with human beings, masturbation to completion is an exceedingly rare phenomenon in other species with capable hands very much like our own. As anybody who has ever been to the zoo knows, there's no question that other primates play with their genitalia; the point is that these diddling episodes so seldom lead to an intentional orgasm” It’s a pretty involved article but the frequency difference between us and other primates is also interesting.. “There was plenty of sex, particularly during the females’ peak swellings. But just two incidents of male masturbation leading to ejaculation were observed. Yes, that’s right. Whereas healthy human males can’t seem to go without masturbating for longer than 72 hours, two measly cases of masturbating mangabeys were observed over a nearly two-year period”. “University College London anthropologist E.D. Starin didn’t have much luck spying incidents of masturbation in red colobus monkeys in Gambia, either. In a brief 2004 article published in Folia Primatologica, Starin reports that over a 5.5-year period of accumulated observations totalling more than 9,500 hours, she saw only 5–count ‘em, five –incidents of her population of five male colobus monkeys masturbating to ejaculation, and these rare incidents occurred only when nearby sexually receptive females were exhibiting loud courtship displays and copulations with other males” Anyway thought it may be of interest to others..
