You should definitely go see it, but it is sexually graphic (especially the first couple of minutes). The main character makes comparison between sex and porn, and explains the downsides of sex and why he finds porn more satisfying. Basically fantasy vs reality. There are little things in the movie that make me lol because I knew what he was talking about and other things I don't want to spoil.
....Yep. Watching it now. This movie actually may be my biography.
