This is a bit of a strange thread but my sister mentioned to me that she saw a fertility programme a couple of months back. One of the things it looked into was the reason for the female orgasm. They seemed to imply on there that historically the only reason for a woman to orgasm was that it causes the womb to contract and 'vacuum' up the sperm, therefore increasing chances of pregnancy. Did anyone else see this, or hear this kind of thing before?! Well of course having heard that I am trying to make sure hubby comes first when we BD to maximise our chances. Oh my, what lengths we go to eh ladies?!
