The movie's plot is centred on the making of an amateur porn movie. Some sexual contents are expected.
That said, this movie is not nearly as vulgar, obscene, or nudity-filled as one would expect, as it is comedic and not very serious for the most part. The amount and graphicness of the adult scenes is extremely low. There is a surprising lack of moaning and other sensual noises. So, despite the plot, this movie is quite harmless and safe to watch, even if it obviously isn't aimed at children.
The women involved in the making of the movie may wear suggestive clothes and sensual lingerie, but it is not very revealing. There is so nudity.
Two men strip in close-up. We see the butt of one of them, but it's quite far from the camera.
We see another man's butt for a few seconds.
A woman rubs the crotch of a men (very briefly and only outside of his trousers).
A sex scene between two men and a woman takes place, but it is highly comedic in nature, and we don't see anything at all.
There is a lesbian sex scene, but we don't see any graphic detail.
Apart from those, there is very little nudity, and overall none of the sex scenes are shown in detail.
