Lady Dynamite (1983)

Though a wife's doctor is the kind who prefers to undress her and inject in her backside, his routine examination does reveal she has gonorrhea. Furiously knowing she could only have gotten it from her husband, she separates from him and immediately mounts a lover. Next up, she visits her friend's yacht and tells him she finally wants to be more than friends. The wife then goes to a women-only sex party. Eventually, the party host invites male strippers who even manage to convert a lesbian guest. The wife then agrees to forgive the husband if he gives her the same passion she says he must have given his lovers. But it turns out she just wanted to know what his passion felt like before leaving him for good.
