Beat 'Em and Eat 'Em
Possibly the least erotic concept for a game imaginable, Beat 'Em & Eat 'Em is a Kaboom!-style game for the Atari 2600 that featured a man vigorously masturbating on a rooftop while you controlled two nude women trying to catch his seemingly-endless sputters of pixelated-ejaculate in their mouths. We are not making this shit up. It was released by early porn "specialists" Mystique in 1982, the same people we have to thank for the next game on this list – the tasteful majesty of Custer's Revenge. A gender-reversed version of the game was later released as Philly Flasher, which had you catching falling breast milk that was being lactated by a witch on a rooftop.
