Doesn't anybody else find this outrageous?

I can't believe how out of control society is. As an active movie goer I've found that you can't go into any movie today (except G and PG rated movies) without seeing and . Its even in PG-13 movies! I'm sorry but no 13 year old should be watching people have on the big screen. I have grown up thinking is meant between two people in love behind closed doors. Young girls (and guys) watch this. Suddenly kids are having at 12 and 13, girls are going anorexic, and pretty much all people admit to having self esteem issues. If and s are so important in a movie its just a sucky movie anyway! Back in the 1950's pregnancy wasn't even mentioned and couples on t.v. slept in seperate beds. Now t.v. shows, show just about as much as they can. And what about your children? Do you feel okay allowing them to watch movies and shows where its portrayed as fun to have , and cheat on their spouses, and skinny girls are admired and fat are looked down on. As a teenager I dealt with depression. I had very low self esteem because I felt I would never be as good as those pretty girls and my body would never look like the ones on the movies. I think the movie "knocked up" took it TOO far! Showing mulitiple sex scenes. And even a women giving birth! Shouldn't this be stopped? Is all that really nessacary to put in movies? What are your thoughts?
