Due to the UK's Obscene Publications Act we Brits have a strange time watching any porn (imported or home grown).
Legislation in the UK means that we cannot see any erect penes or penetration. You can imagine the effect that has on hardcore pornography.
The camera angles change sharply and panning cuts off suddenly. We are treated to many shots of mens midriffs and the tops of women's heads bobbing back and forth. Sex scenes go directly from undressing to frantic climax, or (much worse, imho) cut from a couple halfway through lovemaking to some bad pornstar acting.
Now watching porn is not sad or wrong. After all it's only moving pictures and sound, performed by consenting adults. What I find some damned annoying is that fact that someone else (probably in their sixties) has decided what I can watch. They don't even know me! How can they know that seeing Asia Carrera in a luscious lesbian love-in will scar me for life (even at 25?)
Grrr, censorship sucks
