The problem is anyone, especially older people, who complain about any of this are accused of being "prudes". They forget most of us were teenagers in the "swinging 60s" and there isn't much we haven't heard, seen or done!
I don't want to watch a programme which includes a couple of naked people going at it, especially as it rarely has anything to do with the story line.
Anyone else notice that in these programmes it is usually the actress who is filmed naked whilst the actor has a blanket discreetly covering him - why aren't these actresses, who are usually so vocal about feminism, refusing to do these scenes.
