Ida Sabelis and her boyfriend Jupp had sexual intercourse in an MRI machine in the name of science back in 1991.

While their lovemaking session happened over 30 years ago, it recently captured attention again after the remarkable images were shared online, leaving many in awe at the “wild” measures they took to get the snaps.

Ida and Jupp got physical inside an MRI machine after their friend, Dutch scientist Menko Victor “Pek” van Andel, set out to uncover what happens inside our bodies when we have sex.

The images generated were the first of their kind and became the center point of a hugely popular British Medical Journal entry in 1999 when a more detailed study was conducted that is still read by thousands of people every month.

One of the most remarkable findings from the experiment was that a woman’s vagina wasn’t simply a straight tunnel.

It had been a long-running belief that a man’s penis went in straight and came straight out, with early depictions including the famous Leonardo da Vinci drawing from 1492 showing the vagina as a straight cylinder.

But the MRI showed “the penis has the shape of a boomerang,” meaning it bends inside to the shape of the woman’s body, without any pain to the man during his erection.

The discovery was huge, leading to a formal study conducted between 1991 and 1999 by Ida and Pek, the results of which were published in the BMJ.

These subsequent experiments were all done in the missionary position, using volunteers above the age of 18 who could quit at any moment.

Take note of where her erect clitoris is making contact with is body. They had to lie perfectly still in the machine but it's not hard to imagine the clitoral stimulation created by movement... especially hers.

Wonder if they ever thought of two guys barebacking? Just curious what that would look like. They should also try different positions.
