I’m 99% sure the movie was in the 80’s maybe very early 90’s. In English and in color.
One scene I remember was that at the pool one of the locker rooms was closed (I can’t remember if it was the male or female locker room). The main character was showering after swimming and had his eyes closed letting water run down him when 10-20 girls walk into the shower. He didn’t hear/notice them. One of the girls drops her towel and starts showering next to him when he finally notices her.
