JimLur, It wasn't mathematics and measurement, you fool. Use your head. I'm not surprised
you went to a school that did not have personal development/sex education classes. Idiot.
Edit. And if you don't understand why so many, even adults today, are still uncomfortable
discussing the genital region then you should understand the positive value of such lessons.
It was Plato who said, “He, O men, is the wisest, who like Socrates, knows that his wisdom is in truth worth nothing”
