And if I may add, part of the fallacy of the streak/perfection/relapse mentality is that it doesn't look at the issue in a global way.
Let me explain. A couple of years ago I had a very rough Yom Kippur, and really wanted to change, and really wanted to make even the sincerest of small kaballahs, but I knew that I couldn't honestly commit to EVEN THE SMALLEST REDUCTION in my acting out. So instead I made the following kaballah which I knew I could keep: I would keep a meticulous cheshban of my acting out (as well as some other aspects of my yiddishkeit). Whenever I act out, I record it, whether it was just looking, or more, where it happened, stuff like that.
Many interesting things have occurred as a result of this cheshban, but whats nogeya for this thread, is that it became abundantly clear that the yetzer hara makes his business in volume (הכל לפי רוב המעשה), and it doesn't really matter to him how that volume comes.
I was able to see clearly how many times I was "clean" for three weeks only to masturbate 3 times a day for the next week. So for the month I masturbated 21 times, which is almost once a day.
I was able to see how much I was getting killed by masturbating multiple times when I fell, instead of containing a fall to 1 or at most 2 times. I would use losing money as an example. Say you made a bad stock trade and lost 10,000 dollars, do you go ahead and make 2 more dumb trades to lose 20,000 dollars more? No! You try not to lost a penny more! Same thing. You gave in, lost control, went to a bad psychological place, and masturbated. You don't want to masturbate again! No way!
Sorry for being long winded, my point in all this bnogeya to you is that you have 2 ways to look at this:
1) I am a relapsed addict who is only clean for a measly 2 weeks (estimating) when at my best I was clean for 4 years. Woe is me. ("And maybe I should masturbate now because it will feel good and what's the point anyway")
2) I've masturbated twice in the last 4 1/2 years. That's amazing for anybody, addict or not. And I used to masturbate 3 times a week on average so that would be 702 times over 4 1/2 years.
I reduced my masturbation from 702 times over a 4 1/2 year period to 2! I am the biggest tzaddik to ever walk the face of the earth!!
Between these 2 choices....!ובחרת בחיים
