Looking for Asian love story mistress

In the end she is cutting his genitals
1980’s or early 1990’s
The cover is the face of the girl, black hair, black and red
Little bit erotic
They have Roman, maybe he is married
In the end while sleeping she is cutting his penis

In the Realm of the Senses is from 1976 but ends with castration.


The cover of the Studio Canal Blu-ray might be what you're describing.


It's based on a true story of a woman, I think only known as Sada, so there are some other movies based on her (life), so it's possible you might be thinking of a different depiction of her (or a different movie altogether).


But that's my current guess.

Yessss! Thanks
