I wonder too. And those who did- I wonder if they bothered to teach you anything?
Yes, we mystify sexuality way too much. It can be mystical, but doesn't have to be- completely personal choice. And I for one believe it should be an informed personal choice- not brainwashed into us as children.
Sex is he whole reason we exist. It is the most primal urge and basic reason for doing most of what we do. Whoever decided that we had to stem our passions was truly brilliant. No better method of social control.
