What is really missing is good sex education in schools, especially public schools - and in particular in the United States. The state of sex education in America actually deserves the work deplorable, it's so bad.

Looking at this comment thread, I get the sense that people are coming from vastly different backgrounds and upbringings. There's no baseline established for what people are trying to discuss.

There are a lot of topics that should simply be explained to children up front from a very early age. When a topic is not shrouded in mystery, it becomes boring. So kids should learn from an early age what is sex, puberty, menstruation, homosexuality, etc. and it should be presented in a manner-of-fact way that takes the emotional charge out of the picture. When people are educated, they have more latitude to make good decisions.
