This movie is set in the 70’s I think and it had this young blond guy who was in this place, not sure if it was a insane house or what but he was sick and he talked to a psychiatrist a lot and he had this problem where this white marshmallow like substance came out of his skin and everyone that knew about it wanted to eat it. One scene shows this little kid rubbing the stuff off the mans stomach and eating it. It was a strange movie and I cant think of the name of it.It wasnt sexual or anything like that, just weird. I remember the guy was dying throughout the movie also.
