[SCENE REQUEST] Vintage female therapist scene

I’m looking for a movie title &/or actress from 70s/80s. The scene has the hot big boob & fit female therapist (for some reason I think she favored Annie Lennox of Eurythmics) helping a young man to control his excessive masturbating. She does so by masturbating with him in her office. It’s really hot & so is she. The guy was made up to look/act like a nerd & had super short shorts on. She was shaking & really really looked like she was cumming & saying repeatedly “That’s a good boy”
Plz help yall!!
