Not too much to say about this one...pretty interesting.

MRIs Are for Lovers: Sex in a Scanner

Back in the 1990s, Dutch researchers stuck couples into MRI machines and took scans as they had sex.

Above is a scan of one couple sharing an intimate moment. (Click on the picture to, ahem, make it larger.)

Here's a key to the letters in the image:

P=penis, Ur=urethra, Pe=perineum, U=uterus, S=symphysis, B=bladder, I=intestine, L5=lumbar 5, Sc=scrotum

So what does this tell us?

Here are some take-home messages, courtesy of the study (which is eight years old but among the top viewed stories today on the website of the British Medical Journal):

Quote:

During `missionary position' intercourse the penis has the shape of a boomerang

During female sexual arousal without intercourse the uterus rises and the anterior vaginal wall lengthens

The size of the uterus does not increase during sexual arousal

My favorite part of the study:

Quote:

We did not foresee that the men would have more problems with sexual performance (maintaining their erection) than the women in the scanner. [Blogger note: They actually had to bring in Viagra.] All the women had a complete sexual response, but they described their orgasm as superficial.

Is it just me or does this dude not have legs?

So THAT'S how it works... I've been doing it ALL wrong.

Damn kinky scientists... I bet they have a centrefold in their report.

Come on, somebody must be able to explain the legs! - 'cos I can't

I didn't think there would be enough room in an MRI for two people to get it on...

If I understand how an MRI works they take pictures that are represented as slices. What you are seeing is 'slice' of this couple's insides that best displays how their genitals interact.

Given that most people's legs are on either side of their genitals, the legs are not going to appear in that particular slice. The stumpy bit at the bottom is just the bit of the top of his leg that does appear in the slice. You will notice the woman appears to have no legs whatsoever, this is likely because her legs are spread while his are together. Typical missionary position.
