Hollywood has pushed the limits of censorship and good taste for many years. But the box office returns speak volumes about its success. My favorite example is not a movie but the TV Series - Petticoat Junction. Three young women skinny dipping in a water tank in a town called Hooterville in 1963. How the writers pulled that off is an unanswered question. Your point is well taken, unfortunately, the list should have hundreds of films on it.
