Vapors (1965)

Curious but closeted married man Mr. Jaffee decides to take a walk on the wild side one night over to the local bathhouse located in Times Square. When approached by Thomas, a swinging regular who takes an interest in Mr. Jaffee as the new face 'on the scene', a deep discussion about marriage, connection and loss unexpectedly unfolds. The two become emotionally intimate within a very short time, with no sexual contact of any sort, while everyone around them are screwing like rabbits.
