The reason we all participate in oral sex seems pretty simple: it feels god damn great. It turns out, however, that there may be more to it than fantastical foreplay. A recent study conducted by Medical Daily has revealed that there could be other reasons we engage in oral sex.
According to a study in the Journal of Reproductive Immunology, swallowing semen can make your body more accustomed to an S.O’s DNA, which limits your immune system’s crazy when you are pregnant. It seems that introducing the body to the babies fathers ‘foreign’ genes before you get knocked up will help you out with all things morning sickness, mad woman hormones, and cravings that rival those of a carb-loading body builder.
When a man goes down on you, a study in Evolutionary Psychology revealed that it is all about him wanting to prevent you from cheating. It turns out that if a man knows that there are others romantically interested in you, he is more likely to make you orgasm through oral sex. This competitive introduction to going-downtown prevents sperm competition and helps men pass on their genes (so caveman-esque). We ain’t complaining!
On top of all this, there is the fact that oral sex leads to intercourse that leads to reproduction (which seems like a no-brainer). Yay for oral!
