How can this possibly be rated 4+??? – Weird Facts 1000! Cool & True! Review

We purchased this for a cart of ipads for a school based on the rating of 4+. There are facts such as "75 % of sex toys are manufactured in China, "The longest erect penis ever recorded in history is 13 inches" and "An average man ejaculates about 40-600 million sperm each time". Have you lost your minds? I don't have an issue with the content for adults, but do not market this to children!
