Hi

i'm looking for classic movie ( maybe french im not sure).
Its from around '80. I dont know the name of actors, but i remember one scene.

The man was in clothes store and he was looking upskirt of female mannequins, and he saw a pussy all time when he watched ( he was obsessed by sex) and he had flashbacks about his ex girl friends.

thank you and sorry for my bad english , i'm french.
