Considering the amount of implied or softcore sex that's featured massively in music videos, soap operas, films, other TV dramas and gossip columns, I don't see the point in blaming pornography for children being subject to sex early.

Ultimately the responsibility is down to the parent. You can either let it be and let them discover how wonderfully warped adulthood is for themselves, or impose all sorts of filters and restrictions and they'll find it at a friend's house. It's a ritual of puberty and adolescence, I don't think many 6 year olds are Googling penises. And whilst I personally find it a bit disturbing for anyone under 13 to find it (and that in itself is an interesting point given the age of consent, because it's pretty much commonplace for people to lose their virginity before 16 nowadays), I believe others don't. I don't judge them for it, because ultimately it's just a penis. Only when grooming, paedophilia and abuse come into play should it be a problem.
