In this this video, Lou Paget discusses the types of orgasms that men and women can experience. According to Lou, women are capable of ten different flavors of orgasmic pleasure, while men enjoy eight.
Both men and women are able to experience mouth, nipple/breast, anal, blended, and zone orgasms. Paget also mentions that the different varieties of orgasm feel different because they ensue from different neural pathways.
Clitoral and penile orgasms result from stimulation of the pudendal pathway, while orgasms that result from G spot, vaginal, and rectal stimulation often involve the pelvic nerve. Stimulating the pelvic nerve, via the rectum, can also lead to pleasure in some surprising ways.
According to Barry Komisaruk and Beverly Whipple in their book The Science of Orgasm, one guy claimed that every time he took a dump he experienced something like an orgasm or an ejaculation - most likely due to inadvertent stimulation of the pelvic nerve (a type of neural "cross talk"). This also occurred during a strong urination. He experienced other odd symptoms as well, such as an increased pulse rate and extreme fatigue. The researchers claimed this went on for something like ten years! (Gee, it's a wonder he ever got out of the toilet).
The cervix is connected to three different nerve pathways: the vagus, hypogastric, and the pelvic. In an interesting experiment, Komisaruk and Whipple devised a unique cervical stimulator, essentially a diaphragm that had suction capabilities in order to study how the cervix responds sexually. The device was a huge success and one enthralled woman said it created a uniquely pleasurable sensation that felt like a "shower of stars". Stimulating more than one hot spot (i.e., vagina and clitoris etc.) at a time combines sensory information from different nerve pathways creating the blended orgasm (a much bigger band for your buck).
Our bodies are capable of some amazing things. But it's important to keep this information in perspective. Even if women are physiologically capable of ten different types of orgasms, many women struggle to have even one type, or even one orgasm. Not every woman is going to have a vaginal or G spot orgasm. And most women orgasm primarily from clit stimulation. It's interesting to me that men's orgasmic capabilities are still largely ignored. For example, while many women spend countless hours in a fruitless search for their G spots, often feeling like failures for their inability to manufacture the orgasm du jour, few men seem all that interested in digging in their behinds for a prostate gland (the unsung male equivalent of the G spot).
I would like to see more men look for their "great eight", and more women accepting of their unique orgasmic capabilities. Anyway, here's Lou...
