Here's a little article I picked up from WebMD.com about orgasms.

Orgasm Brain Spot Identified

Feb. 1, 2002 -- The makings behind an orgasm are tough to figure, given it's difficult for medical research to perform adequate tests. But thanks to an unusual seizure phenomenon, researchers have pinpointed the area of the brain responsible for orgasm's pleasurable sensations.
A 31-year old woman had been keeping a secret from her doctors for nearly a decade. Before each seizure, she experienced an orgasm-like feeling.
This spurred the researchers into looking for other people who'd experienced this intriguing "orgasmic aura" phenomenon. Jozsef Jansky, MD, and colleagues found 22 other cases in which a person with epilepsy experienced orgasmic sensations just prior to having a seizure.
That led Jansky on a search for the area in the brain responsible for orgasms, something that had eluded researchers until now.
Most people with this type of seizure described their orgasmic auras as feeling very similar to what they'd experienced during intercourse or masturbation. The researchers say this is evidence that the special nerves in the brain are an integral part of an orgasm -- especially given that orgasm may occur with an active imagination and no physical stimulation.
After performing brain-wave studies on each person, the researchers found that an orgasm starts in the right side of the brain. And the right side of the brain does, indeed, seem to play an important role in human sexuality.
Production of hormones controlling sexual functions is more commonly controlled by the right side of the brain. Sexual arousal is associated with activation of the right side of the brain. In fact, during masturbation-induced orgasm in men, the researchers say that the blood supply to the right side of the brain goes up.
The woman that sparked this research went on to have surgery for her seizures. The part of her brain that was causing her seizures was removed. One month later she had two seizures, without the orgasmic aura. She has since been seizure free for three years.
The researchers hope that this research will lead to a better understanding of the origins of orgasm. This could also help ignite research into specific treatments for people suffering from difficulty achieving orgasm.
