I realise I'm not giving a lot of info but I remember these 3 films being the first I watched as a young man, and I've never been able to find since!

One is a scene from a compilation. Late 70's/early 80s. An older woman/cougar with a younger guy. She had ginger hair. I always remember her saying "his jockstrap size large- it's too tight!"

The second is a German film from the 80's based in a ski camp. (I know, a lot to go on there!)

The third is an American film from the late 80's/early 90s. There were doctors and nurses in it. What stands out in my mind was it was the first time I had seen candle wax used in a film!

As I mentioned, not a lot to go on, but thought I would try!
