There is a sex scene with a woman going down on a man sitting on a chair. In the last scene there is a long sequence with a topless pole dancer (at least in the european version of the film).
Matt is sitting between two girls on a boat. He has one of his hand on the thigh of a girl and with the other hand he is fingering the other girl's vagina. Though nudity is not visible, his movement under her skirt is clear.
