Sex is a lot more of an art than a science. It is simple to teach the motions. Even to just show them through porn. What is very complex and extremely personal and variable is what it is exactly that you like better and that you are indifferent to, or even bothered by. That can only be discovered through personal practice. For instance, a standard sex class for a boy may include a unit about big bewbs and what I am supposed to do with them. But since my AOA pretty much eliminates big bewbs, that unit is useless to me. OTOH, while a unit about a naturally bare pubic area would be very useful, you bet there won't be any. And this is just by AOA - it really gets more complex and more personal once you are talking about likings and dislikings which are not the product of different body parts.
