Her sexual response

orgasmic phase

---

Orgasm, the release of sexual tension, involves many bodily changes. While no one is really sure how the nervous system or biochemical systems trigger an orgasm, what is known is that physical and psychological factors are important. Interestingly, physical stimulation of the genitals is not essential for orgasm; some people can have orgasms simply by thinking erotic thoughts.

In women, orgasm is mostly concentrated within the clitoris, vagina and uterus. An orgasm is accompanied by powerful contractions of the uterine, vaginal, anal and lower abdominal muscles.
