In the UK we used to have a watershed time of 9 oclock... before which, nothing more than heterosexual kissing was allowed. Most kids now tend to watch the soaps and sad to say they see a lot of adults and young people jumping into bed with each other as soon as they meet.. as well as many other unsavoury things which would not have been acceptable when the watershed was set..... Just another of our values which has slowly been watered down... amongst thousands of others.
Best wishes, Mike.
