just because it's bound to be talked about...sex addiction isn't in the DSM-5

7. I agree that it is complicated.

But I find it easiest to place it in the realm of compulsion. An overwhelming impulse to do something that is temporarily gratified by doing it only to return and is pursued despite significant negative consequences.

I don't think compulsions are drives to reduce anxiety. I think they are drives that produce anxiety - overwhelming anxiety - which is relieved by giving in to them, at least temporarily.

Impulsive behavior is different and can be much more readily controlled.

Some impulsive in my elected officials is ok. Serious compulsions, otoh, is much less acceptable as those will drive people to make some really horrible decisions without regard to the consequences.
