Definition
In both sexes, orgasm can be derived during anal sex [ANAL INTERCOURSE]. It is possible for men to achieve an orgasm through prostate stimulation. The female prostate is located next to the rectum. For women it's still unclear which structures are involved. [1]

Anatomy
Basically, the anus is a highly sensitive region. Most people experience pleasure through touch alone. Its stimulation by finger, penis or adequate sex toys leads to pleasure which spreads out in the entire female abdomen. Some assume that through anal penetration the A-Spot or the uterus are stimulated [1] [2], while others believe that the G-Spot or the clitoris are responsible for pleasurable feelings. [3] [POINTS OF INTEREST] [CLITORIS] It's possible that the combination of all these factors enables anal orgasm for women.

Studies and surveys
The „National Survey of Sexual Health and Behavior" [4] is a very comprehensive US-study which has found out that women have a high chance of orgasm during anal intercourse; in fact, the chances are higher than in any other form of sexual stimulation. [1] [4] Anal orgasms are often described by women as very intensive, "like an earthquake" or as a "wild and racing sensation in the abdomen". Some also describe it as the highest form of pleasure and happiness. [2] [3]
