Ah, got it. Thanks very much for the explanation. The alcohol analogy makes it lucid. When it comes to pornography I'm definitely a "glass of red wine with dinner from time to time" kind of person (TMI?), so it was out of my frame of reference to know what kind of behaviour you were describing.

"I would notice that I would put so much stress on my body, that it would really take me about a week to recover and feel normal, and then the cycle would start again" sounds, well, pretty wild and probably jolly good fun to be honest, but I can see how that could be problematic as a regular and difficult-to-resist habit rearing its head every week or so.
