It’s no secret that many women have multiple orgasms. Masters and Johnson documented this occurrence more than 25 years ago. But, do they serve a purpose besides from a pleasurable one? Theories suggest that muscular contractions associated with orgasms pull sperm from the vagina to the cervix, where the sperm can then swim their way to the fallopian tubes to reach the egg. Researchers believe that if a woman climaxes up until 45 minutes after her lover ejaculates, she will retain significantly more sperm than she does after non-orgasmic sex.

We will talk more about multiple orgasms later.
