You and I have different experiences. When I was in seventh grade, sexuality was most definitely "discussed" and quite often yelled. They didn't have sexuality when you were in seventh grade? No "school steady"? No dances? No dates? How about sixth grade when the precocious couple got serenaded with "Bobby and Jenny sitting in a tree... k i s s i n g"?
That's not sexuality. That's juvenility, much like playing video games doesn't make one a programming expert.
