Robin saw the 2-part film Nymph()maniac by Lars von Trier from 2013.
Nymphomaniac Joe (Charlotte Gainsbourg) is found beaten up in the snow by middle-aged bachelor Seligmann (Stellan Skarsgard), who takes her home. There she tells her life story. Seligmann eventually confesses that he is still untouched.
The truth about Seligmann unfortunately makes the end of the frame story somewhat predictable.
The heroine’s life story also doesn’t explain why she became a sex addict. (One possibility, for example, would be commitment anxiety with sex with constantly changing partners as a substitute for deeper relationships.)
On the other hand, Robin found the exceptionally good acting performances positive.
