Life is wasted on the living. Love is a matter of chemistry, but sex is a matter of physics. You will see the light at the end of the tunnel. Unfortunately, it will be the light of an oncoming train. It's a hardware problem.
Sex is hereditary.
If your parents never had it, chances are you wont either. Anyone can hate. It costs to love. Words must be weighed, not counted. Take care of the luxuries and the necessities will take care of themselves.
