Funny, yet not
This is not sex addiction, but serious self-harm, and is in fact an exhibition of insanity. Because it's about sex, it seems funny, but this poor woman is abusing others and living a life of self-damage and disfunction. 'Nymphomania' is always a joke, but these women are usually victims of childhood abuse. Just read (if you can bear it) stories of rescuing 12 year old girls from brothels, or indeed young boys from brotherls -- their actions and reactions are nearly the same.
