It is probably fair to describe this piece of direct-to-video exploitation fare as a modern C-movie. The typical B-movie has more plot, more character development, and better production values than this cheapo, but it is still a couple of notches better than the pitiful embarrassments from the bottom of the range.
This erotic thriller centering around a radio psychiatrist may claim inspirations from Play Misty for Me and Frasier but in truth it has a model much closer to home: Sexual Response, a relatively successful B-movie with video queen Shannon Tweed. The focus here is on sex, not on violence, and the sex scenes come just as thick and fast as in a porno - except that this is strictly R-rated. The UK version (which is the one I saw) is 3 minutes longer and presumably a little more daring than the US release.
