Who invented oral sex ? OriginConsidering its current popularity as well as its depth in recorded history, oral sex is thought by many to have been a part of prehistorical human sexuality. Hence, some theorise that its origins are biological, and not simply carnal. A study published in the British Journal of Medicine showed a correlation between oral sex and healthier newborn children. Semen, when ingested orally, is thought to familiarise the female immune system with the male DNA, lowering the risk that male genes would be rejected, and thus the reduce the risk of birth defects. One hypothesis points to the possibility that the apparent connection may be a biological evolutionary trait, which favors reproduction among couples who have more long-term and intimate relationships than others.http://en.wikipedia.org/wiki/Oral_sex
