Obviously this was written by a guy who likes his lady to go downstairs more often lol.
A New York University did a study about how happy us girls are after we have perform oral sex on a guy and swallow the evidence of his passion.

Seems we get a little Cock-tail (sorry for the pun) of happy boosting chemicals found in semen which include:

• Cortisol – known to increase affection
• Estrone and oxytone – which both elevate your mood
• A hormone which releases thyrotropin, an anti-depressant
• Melatonin – a sleep inducing agent
• Serotonin – an anti-depressant

Just remember don't have unprotected sex unless you have a trusted partner and no means no if you are pressuring someone to do something they don't want to,
