This may be more information than most want to know but I can relate to the content of this article from my own experience. I went through adolescence in the "Leave It To Beaver" era of 1955/1956. I was also raised in a very strict household where sex just wasn't discussed.
When the inevitable began making changes in my body I got very little useful information from my parents. Instead of relying on hand-me-down questionable information from my peers I decided to seek the best answers I could. The Free Public Library turned out to be my best source of information.
By the time that I had reached the age of 13 I was completely versed in the reproductive systems of virtually all warm blooded creatures including the human animal. I could explain the onset of menses and the complete menstrual cycle of the female and the entire reproductive system of the normal male. I also understood the process of conception and how the sperm sought out and competed to fertilize the female egg.
I had seen movies of every kind of birth there is from normal vaginal to "C" section and from breach to cord babies. So I would say that I was actually better informed than most adults in 1957. However the one thing that I did not get from all of the books and films was how a relationship worked and how to deal with it.
That is one thing that there simply was a dearth of information about that was readable and understandable by an average youth who did not have a psychology or psychiatry degree. As a result I was very awkward and uncomfortable in trying to start a relationship with a young lady.
Fortunately I was basically chosen and cut out of the heard by a very intelligent lady who knew what she wanted and wasn't put off by my awkwardness. As a result we had forty years of happy marriage that produced two fine sons so I didn't miss too much. However as this article points out that is an area that really needs to be addressed.
I have long supported comprehensive sex education that not only covers the mechanical aspects of sex but also clearly explores the emotions and the social parts as well. How to deal with rejection, how to begin a relationship, what to expect in a relationship, how to regard your partner in such a union, and finally how to deal with a breakup are all critical areas that should be taught at some level.
