Courtesan (1983)

In the 19th century, a Japanese prostitute is about to move to America with her lover when he dies. Saddened, she moves to America alone and becomes a successful prostitute. However, her dead lover reappears on her knee as a mole, which she kisses. Her customers, feeling that this is weird, abandon her; she asks her husband to return to the spirit world, on the condition that she would never marry again. He returns, but a few months later she marries an American millionaire. On the night of their honeymoon, the prostitute's vagina is possessed by the vengeful spirit of the dead lover, which causes the millionaire's penis great pain.
