If it wasn’t clear before, there should now be no mistaking it: You don’t want to watch Fifty Shades of Grey with your mom.

The film adaptation of the wildly successful E.L. James erotic novel will include roughly 20 minutes of sex scenes in its 100-minute running time, according to the Sunday Times. This means that about one-fifth of the film will involve people getting better acquainted, if you get our meaning.

Jamie Dornan, Dakota Johnson, Marcia Gay Harden and Luke Grimes star in the film that centers on a student who takes a shine to a troubled businessman. And (spoiler alert) they get it on a lot.

Watch the trailer:

Fifty Shades was directed by Sam Taylor-Johnson and is tracking for a big opening-weekend gross.
