There is a category of addicts who identify as Sex and Love addicts.
Great website, with great resources.
Some people can't separate the two, some people identify with one more than the other, some go looking for help for one and discover the other. Sex addiction is way, way more than just getting off.
This could also include NRE junkies. How far one wants/needs to identify gets into how much harm is caused in one's own, or other's lives.
