I think porn has ruined a generation. Ten or so years ago I had some very frank conversations with some of my younger cousins about their expectations around sex because I was younger and I guess easier to approach about it than parents. The girls at 12 to 15 were asking about Brazilian bikini waxes and the noises they had heard they were expected to make and whether they had to or not. The boys, similar age range, then just seemed terrified of the concept of real life sex. None of them had ventured further than kissing at that point.
I was horrified at the time and told them (with parents' ok and in an age appropriate way) that real sex should be fun and joyful for both parties, is sometimes ridiculous rather than sexy, and that it should only ever happen with enthusiastic consent on both sides.
As my friends now have children who are heading towards their tweens, I am saddened and terrified by the way extreme porn has seemingly become the norm.
