When did your parents start letting you watch R rated movies?

I know you have to be 17 to "legaly" be allowed to see R rated movies, but most of my friends have seen movies like the hangover, and orphan and the movie with the baby powder footprints, but i'm not allowed to. The only one i've seen is stand by me. WHen where you allowed to watch the movies? (my mum is very protective, i JUST got a cell phone on like, the 4th day of summer BTW: i'm 14)
