Its not always because of children imitating tv. Children start going through puberty at the ages as young as 5-10 now. and with those hormonal changes comes the natural sexual urges of what feels good to the children and so on. mentally they may be too young for sex and making out and so on but biologically they are not too young which is why many schools now have sex education classes going in the lower grades of K-2 and sometimes 3rd of good touch and bad touch and in sometimes 3 but usually starting in 4th grade the sex ed classes include the reproductive organs, the pros and cons of having sex and birth control and so on.

I got a call from my sons kindergarten teacher one day because My son at age 5 had his unexpected erection and release during school and he needed a change of clothes. I took him to our family doctor who explained things a bit to him and then at age 8 he had complete sex ed class in school.

Its not just movies and kids copying movies, music and books. most of the time its because of natural biological course of life.

Sometimes I think of how things changed since I was a kid is that biologically things are reverting back to the laura ingalls wilder days where children as young as 12 and 13 were getting married some because of a baby on the way or has been born.

Childrens bodys are just back at that time frame where they are maturing at ages 8-10 instead of 16-18.
