well my moms is a cna and when she told me she just finished school. i could tell that by looking @ her she was uncomfortable. so what she did was take out one of her thick nursing books opened it to a page and told me to look "this is a man's anatomy" then she flipped the page and said "this is a female's anatomy" read this about the human reproductive system. and she walked away. that's how i learned in the 5th grade. she hasn' brought the topic us since so anything else i learned from then was from the fast girls and the foulmouthed bwoys in elementary school and high school.
