Interesting Sex Documentary I Watched Last Night

I saw the most fascinating documentary on human sexuality last night on one of the learning channels. One researcher found via trials that if a woman had an orgasm she has a "greater" chance for conception because the contracting muscular spasms pulls sperm faster up towards the fallopian tubes due to a suction kind of mechanism, and the cervix goes down and up during climax which dips into the pool of semen which helps as well. That...I did not know. So, guys? Want a son or daughter? Don't stop--just keep-a-going. LOL
