Beyond the Time Barrier (1960)

There is some dialog about breeding. The mutants are sterile, so men are needed to recreate a race of people.

A girl can read the minds of men. When someone thinks about sex, she slaps him.

Some women from the future wear dresses that end slightly above mid thigh.

A woman is swimming and is assumed to be nude, although she is never seen nude and is distorted by the water. When she gets out of the water (off screen) she wraps herself with a large towel and you can see some cleavage.
