sex mri

Here's some rather special dirty pictures. You won't see these anywhere else. They're magnetic resonance imaging photos (MRI) of a man and woman having sex and were taken by Dutch researchers who report their results in this paper.

The picture on the right is a simplified diagram of the one on the left so it's easier to see what's going on. The man's body is on the right (you can see his spine), the woman's is on the left. Because they were using MRI, they were able to take a photo like a slice, right through all the business. That kind of bent stick-like thing in the lower middle? Yeah. That's exactly what it is. See the testicle below it? That white thing in the woman's body just above and to the right of the head of his unit? That's her bladder. You can see his bladder too. They're empty, so they show up white.

The amazing thing for me was seeing what they call the "root" of the penis inside his body. The researchers said it's typically about half the length of the external part when erect, and is firmly embedded in the male musculature. Who knew?

They were pretty brave to get these pictures. The research wasn't funded and in fact was done on the sly. They had to sneak their volunteers into a hospital MRI unit during off hours, and how they contorted themselves in order to fit into that tube is beyond me.. Still, the pictures are rather amazing, I think.

If you've ever wondered what it looks like while you're doing it, now you know.
