What movie is this scene from?

My husband and I both remember this scene from a movie which we thought was Cat People. We watched it in the early 80's. We didnt know each other at the time so when we watched it recently together and that scene wasnt in the movie we were both confused. How could we both remember it the exact same way if it were not in the movie? The scene was an erotic scene in which the the two love makers were one behind the other and he was biting the back of her neck just like a cat would do while mating. We remember it being one of the most sensual erotic scenes we had seen at that time. Does anyone remember this scene?

We thought it was Cat People but we watched again recently on the Sundance channel and this scene wasnt in the movie. Do you think it was just left out and would be included on DVD?

Think you are right; sounds like it from the 1982 movie starring Malcom McDowell and Nastassja Kinski as the "Cat People".

Below is more info on the film.
