I certainly wouldn't describe sex addiction as a physical illness, but very possibly as a mental illness in terms of compulsive behaviour and self-esteem issues leading to seeking self-validation through sex. I wouldn't equate it to alchoholism.
The only addiction I would equate to being similar to an actual physical illness would be something along the lines of drug addiction ; This is only because the body is receiving certain chemicals from drugs, and thus is not manufacturing these (such as in cases of chemical opiates). I'm not an expert in drug addictions, but as the body is not manufacturing these, thus is it is an illness if looked upon it from strictly this point of view. The difference thus is the cause of the illness - the body doesn't manufacture these chemicals due to them being obtained from drug use, rather than though the body malfunctioning. The Body is still functioning normally in reaction to external stimuli in this sense. It is thus analogus, rather than actually being an illness; the net result is the same, the causality is different.
it may be driven due to psychological factors such as self-worth, self-esteem , rather than 'poor impluse control'. What are the driving factors behind this behaviour? Is it due to generally, body dysmorphia, whereby self-image is distorted due to a number of external, psychological factors? quite probably, by my reckoning.
Havent seen Hunger. Mind you, Only DVD ive seen is a vanilla ex-rental, and I don't buy vanilla discs if I can absolutely avoid it.
I didn't see the film as about sex addiction as such, but as seeing sex addiction as more a symptom , a product - the manifestation of wilful emotional detachment, and how it affects people's emotional states.
