Young People Fucking is the name of a strange movie. While classified as a comedy, on some situations it feels like an erotic movie. Not that you see too much of the fucking. In fact you don’t, and that might be the reason about it.
In any case, the movie is about a set of couples, and how they react to a sex night, in different situations. For instance, one couple that lost the interest, a couple that are apart for some time, a couple of best friends that never saw each other as a possible mate, and so on.
I think the movie is interesting and can give some clues on all problems that a relationship can raise.
