well don't know.. me hear about it when i was something 5 or 6 years old, but things I was hear, was all totaly wrong, of course. I tryed those things also out my self

it was harmless, nothing like real sex. Don't know, if my parents, or some, told that time to me the truth about it after.. but I surely was not able to hold my big mouth closed and talked to everyone how I did it.. to aunts and uncles, parents and soo on.
But in school there they was teached some.. when I was maybe 16. they did not had even right textbooks about it yet.. I supose that was new thing to them to teach it.. so the teacher had to use a porn magazine help to teach...
