There is an NC-17 version and an R rated version of this movie. The descriptions here are accurate to a point for the R rated version but the NC-17 version includes more female full frontal and more graphic sex (ie., the cream on the boobs is omitted in the R version). The version on Amazon Prime is the R rated version and Amazon does list it as such.
