Ok, I finished this last Thursday. This whole experience has been really good, and might be a good place for some people to start. As you could probably tell, I kind of ran out of steam writing every day and slowly stopped. In the beginning it was pretty useful but then turned into more of a burden than anything else.
I definitely feel like I've grown in this area over the past few months. I see that small steps are possible, but I think that the most important thing that I've learned is how much easier things are if you don't get started looking at stuff. I used to think that guarding your eyes was the final stage of the struggle, after you got rid of masturbation etc. but now I see that it is completely backwards. Be careful what you look at and the urge to masturbate slowly gets weaker.
I also felt like this was too long of a challenge for me. I made it through without watching any porn, but I feel like it would have been better had it been shorter so that I could make adjustments to the plan as needed.
Thank you to everyone who encouraged me along the way, especially Hashem Help Me! I really couldn't have made it this far without your encouragement.
Have I stopped masturbating? No. Am I doing it way less than I have been for the past decade? Absolutely. That's what I call progress.
Here's my next plan. If anyone wants to join, come along for the ride! This one is going to be 30 days long. The commitment is not to seek out any sexually stimulating imagery and find it, whether or not it's pornographic. No browsing sites hoping that I'll "bump into" something "interesting". If I'm looking for bad stuff and find it that's a fall, whether or not I masturbate. If I am bombarded by it, then I need to look away as soon as possible. I'm also going to try my best to take HHM's advice to not visualize anything even when masturbating.
In some ways it's stricter than the ninety day challenge and some ways less so. For the ninety day challenge a fall is porn or masturbation, but looking at bad stuff for a short while is a slip. Here looking for bad stuff and finding it is a fall, but masturbating is a slip.
I will hopefully make weekly posts instead of daily ones, and if I fall I commit to posting it on here soon after.
