In films and TV, when there is a sex scene and the use a sheet to wrap around themselves. As if! Sheets on the bed, are on the bed. Even if you do that odd top sheet thing it makes no sense. It would have to be fully untucked. Then you would need to unsexlily stand up, fold this super king size sheet and wrap it round yourself. Am I missing something? Or is this another case of totally made up stuff that never happens in real life.
