I am sure you have quantify the frequency of sex if you have got
one. ie. it is the frequency of having sex with partner of the
opposite sex, not with your own hands.
I am quite surprise to hear that you are relating sex to mood, love
and happiness. I thought only women talk about that 
Furthermore, I noticed from your posting that you are pretty
adventurous about sex, not sure if that is what you meant by Love
and Happiness?
