I think i saw this movie in the early 90s.  In color.  I am trying to.find a movie where I only remember one scene.  There is a guy and a woman sharing a summer house.  The guy is taking a shower when he passes the girl in a hallway.  He ask her if she wants to share a shower.  But she told him she already had one.   She ends up pulling his towel off and he begs for his towel back.  They end up sharing a shower together.
