Sex is hereditary. If your parents never had it, chances are you won't either. The younger the better. The game of love is never called off on account of darkness. It was not the apple on the tree but the pair on the ground that caused the trouble in the garden.
Sex discriminates against the shy and the ugly.
There is no such thing as an ugly woman. Only too little wine. Before you find your handsome prince, you've got to kiss a lot of frogs. There may be some things better than sex, and some things worse than sex. But there is nothing exactly like it.
