How many types of orgasms can a woman really have?

I'm not sure I have a comment on this story from Salon.com.  But it is rather interesting:

 The elusive female orgasm has been the subject of much scientific debate over the last century.  Some researchers have argued that women can have two types of orgasms through external clitoral stimulation and vaginal penetration, while others believe both orgasms are the same type accessed through different parts of the female anatomy.

In a bid to settle the dispute once and for all, a recent study published in the Journal of Sexual Medicine claims to have solved this age-old scientific mystery, revealing that there are indeed two types of female orgasms … well kind of.

Two French gynecologists carried out ultrasound scans on three “healthy volunteers” by measuring variations in their blood flow patterns to decipher just how their sexual organs moved during different types of sex.

These women were asked to arouse themselves through manual self-stimulation of the external clitoris and through vaginal penetration using a wet tampon. Say what? Both examinations measured the changes in blood flow patterns in the area to ascertain just how the clitoris and vaginal complex responded.

The outcome? The study discovered there is a “functional difference” in orgasms depending on the type of sexual contact.  Specifically, researchers found that only the top of the clitoris responds to external stimulation, while during vaginal penetration both the “root” of the clitoris and the whole clitoral and vaginal complex respond. This affected the flow of blood and therefore produced different sensations in the body.

The study concluded: “Despite a common assumption that there is only one type of female orgasm, we may infer, on the basis of our findings, that the different reported perceptions from these two types of stimulation can be explained by the different parts of the clitoris (external and internal) and clitorourethrovaginal complex [the system of clitoral nerves] that are involved.”

In other words, as Jezebel explains, both types of orgasms are clitoral, but the parts of the clitoris that respond are different depending on the type of stimulation.

So, are these doctors going to further continue this important line of research?  Inquiring minds want to know.
