It all starts with a paper from the Journal of Ultrasound in Medicine, which published a rather curious image of an unborn baby grasping its developing penis. Entitled "Observations of in-utero masturbation," the paper discusses the possibility of this not being just an interesting choice of appendage exploration by the foetus and something more deliberately gratifying.
In the above TED talk, US author Mary Roach talks about all the weird and wonderful medical observations about orgasms that together form a pretty intriguing picture of a phenomenon that is certainly not restricted to the genitals. There's the woman who would experience an orgasm when someone stroked her eyebrow, orgasms from knee-touching, orgasms from tooth-brushing.
There's even a woman who can think herself into an orgasm, and the best part? It only takes her about a minute. Oh and did you know you can technically trigger an orgasm in a dead person? How about a 'semen connaisseur'? Want to meet one of those?
This is one of the most fascinating talks you'll see in a while, so take 15 minutes to take in all the weirdness of the human body. You're welcome.
