Stuffing

Pretty much. Binge eaters want to stop and can't. Stuffers either don't mind gaining or just stuff occasionally so they don't gain.

And it's possible to be both...you get off on stuffing and gaining, and want to stop but can't. Actually if overeating is erotic it can be even harder to stop.

Sounds like you are just a stuffer who doesn't like gaining weight, which is perfectly normal.

Enjoying overeating doesn't mean you have to also enjoy the resulting weight gain, but it does make it difficult to maintain a balance between getting the satisfaction from eating and not putting on excess weight, but it can be done if you stuff with the right foods and counter it with exercise to offset any potential gain.
