I've always had my theories, but now it seems science agrees, women should be swallowing.  Check out the research study that claims oral sex is good for women's physical and mental health. 

If you care about women, you need to expose them to semen.  At least that seems to be the case in a new study done by the State University of New York.  The study found that performing oral sex made women feel less depressed and generally happier about life.  The study claims the change in mood may have something to do with mood-altering chemicals found in semen.

Research indicates baby batter contains chemicals shown to improve overall mood, increase affection, induce sleep and has at least 3 naturally occurring anti-depressants.

The research also shows that women who have unprotected sex on a regular basis perform better on cognitive tests and were significantly less depressed that other women.
