Totally Tubular: MRI Images of Coitus
In 1999, a motley crew of a gynecologist, physiologist, anthropologist, and radiologist, set out to make an amazing discovery. They attempted to find out if it would be feasible to obtain images of male and female genitalia during coitus. The answer: Yes!
We bring you, 11 years later, animated images of their amazing discovery. We here at Crack Home have been, if not enjoying, watching the video.
