The movie contains a lot of sexual activity of a pornographic nature. I personally recommend watching the trailer on YouTube to give you some idea. But it is frequent.

The violence and gore are also of a strong nature, although it isn't believable at all. It is pre-Evil Dead believable

It's occasional. Probably an M rating in Australia equivalent.

The movie isn't believable, so unless you're under the age (or mental age) of 8, it won't scare you. Nor do I recommend showing the film to anyone under 8 due to the graphic sexual nature of the movie.
