Young people now do a lot of things that don't seem all that pleasurable to the auld yins among us. They know about them because sex and the many varieties of it are talked about far more, and having read and talked about it, they believe that everyone except them is practising all the varieties all the time, so if they are not then they are freaks.
The puritanical members of generation before us thought that educating the young about the basic facts of life was going to send them all behind the bike sheds to try it out - in fact, without any information at all their maturing bodies prompted them to try it (usually the missionary position!)
I don't know whether the vast amount of information about the less usual methods is a good or a bad thing for adolescents who have had no experience even of the basic missionary-style. It doesn't leave anything to discover later.
