Thanks Buenchico....but these that you describe in the links ARE extreme cases and not the run of the mill people who just enjoy sex and plenty of it.
Now whether that could be described as "addiction" as maintained by the WHO, that is quite another matter, but on the evidence shown in you link then her life, was affected.
Now whether sex is a matter of addiction or dependency can be argued either way, but i think that it is a dependency as personally i regard addiction as drug initiated.
I suppose one can become "addicted" or "dependent " on anything and these can impact on family life e.g finances, but that is not my definition of ADDICTION.
