I am looking for a movie that I remember from when I was a teenager and would sneak to watch the late night movies on the then new HBO or Cinemax. I thought the name of the movie was Patricia but have never found anything similar to that title. The movie starts with a main character having sex with someone and hitting a single light above them that then swings back and forth. I would now consider it mild soft-core. It looked as if it had been edited down considerably. The plot was basically this woman having sex with a large number of different people. On a boat in what looked like a 60’s or 70’s bikini. At the end of the movie the woman becomes involved in a small orgy. The woman has blond hair. I’m not sure but the movie may have been dubbed.
