Down the Drain (1990)

At the start of the film a man and lady have sex. The lady completely strips and we see full nudity but from the side.

There's another scene where a lady strips. This scene is very prolonged but we only see the lady's breasts instead, but the scene lasts awhile. The two then have sex again.

There's another scene where a guy does a cavity search on a black guy and we see his reaction but nothing explicit is shown except for the necklace he pulls out of the guy's rear.
