Like someone else on this page has already said, this movie should not be approached as a serious period piece, but as a soft-core porn flick. The vapid characters have been stripped of all human dimensions except their sex drive. You kind of wonder when exactly Tom Berenger's character found the time to become a philosophy professor, since we almost always see him in a horizontal position, if you know what I mean. But nobody can deny that the film does have some genuinely erotic moments (Susan Strasberg steals the show in that department, as the always "hungry for more" Bobbie). (**)
