but lots of things in films arent. most 'real sex' seems featured to either get attention or shock.
porn has gotten mainstream enough in the last ten years so i dont really need to see more real sex when i go to the cinema, but it might actually become more accepted these days, rather than just being on the indie/arthouse fringes.
i saw a brazilian film earlier this year i dont remember the name of that opened with a girl giving this middle aged guy a blow job. the film wasnt especially remarkable except for the blow jobs and real intercourse but i wish i could remember what it was called
