What was the first "R"/18-restricted movie you saw?

[Tonchi]

I was so heavily supervised and indoctrinated that there was no opportunity while I was in high school, not even on the sly. There may have been some in our college Humanities film series, but at a Methodist college in North Carolina back in 1963 they probably only showed "approved" material. Cleopatra and Ben Hur don't count as R-rated, do they? Just violence, no nudity or sexual situations, just sticking swords into people instead of something warmer. So the first R-rated film I remember seeing was A Man And A Woman, the old French classic. It was supposed to be so daring, but I actually found it boring. I saw it again on TV a few years ago and I still think it's a boring movie. I guess by the time I ever saw many R-rated movies I was already old enough to be doing the stuff that got them the rating.
