Gosh i allways love reading these kind of topics here on the Escapist.
In my sex-ed class, we learned about everything. From diseases to anal sex. Actually we watched a movie that was about 2 hours long, where one hour was a guideline in having fun, stimulating and safe sex. And yes, that movie showed us positions also. From missionary to the jackhammer.
And you know what? None of us, was uncomfortable with it. Because if your raised in a place where you ain't scared of the human body, the human body is a beautiful thing.
God i love being scandinavian.
