Look at what the education system is doing about "sex education". It is no more than a how to guide and a why it can happen. Sex is never taught that it is for procreation first, they teach it is for recreation and that if you don't engage in safe sex a baby could result.
In other words, sex "should" be just a natural occurance for individual feel good and a "relationship". No discussion of what the natural progression of a relationship is - procreation.
Now, before the "but if you can't have klids...." loonies hop on this the fact some one may be unable to concieve or father a child does not make sex a primarilly recreational activity.
