Why Men Perform Oral Sex

A new study in scientific journal Evolutionary Psychology has attempted to delve into the scientific and evolutionary reasons why men perform oral sex on women. By polling 243 adult men in heterosexual relationships, researchers at Oakland University in Rochester, Michigan, determined that men perform cunnilingus as part of a 'mate retention tactic' to minimize the risk of their partners' infidelity.

1. To increase her satisfaction with the relationship, and therefore minimize the risk of infidelity.
2. Sperm retention; the study notes that previous research has found that women retain more sperm when they orgasm shortly after their partner's ejaculation. They apparently retain more sperm in this way because a female orgasm has been shown to cause uterine contractions, 'which pull sperm further into the reproductive tract'. According to the study, this could be why performing oral sex on women is evolutionarily beneficial, since the retention of sperm promotes conception.
