I wrote the following in response to a man who claimed that if hollywood made a movie of the bible it would have lots of sex, so watching sex in movies is OK:
The depiction of the sex in the bible is never provocative. Even when Absolom rapes his own sister, we are informed that it happens, that she pleaded with him not to, and that is all. We are given essentially the minimum we need to understand what happened, but nothing that is intended to be arousing.
Telling us something of a sexual nature happened, and acting it out for us to see are radically different. I can safely assume you know that your parents had sex. But you probably never watched. The information is different than the portrayal.
