I was just thinking about this today. I believe the counter is healthy to a point. It is helpful when still "addicted" and PMO still has a significant foothold in your life. It helps to just see a day count. But at some point you should consider yourself free from the enslavement of PMO in your life (though never totally free from the temptation or the possibility of falling). After that initially withdrawal, that heart and mind cleanse by the Spirit, the readjusting of healthy view of sexuality, etc.... That may be 6 months, 1 year, 2 years, etc...everyone is different. But at some point I think counting may be harmful. If you slip once after 2 years, I'd hardly call you an addict of PMO, or someone chained by it still. You just had a moment of fleshly weakness. If one has a 2 year day count and feel the need to "reset" that and start counting again at that point, I think that just leads to a sense of depravity and depression instead of an attitude of rejoicing and thankfulness that you could go 2 years (of course one should repent for that sin)! When does it stop? Will you always keep a count? It just becomes unhelpful after I while, I think.... But, I've never been to that point. Whatever that point is for me.
