When all self-control fails, and one seems at the edge of orgasming, and breaking their oath, there needs to be safeguards to break the cycle, to shutdown and restart the system. I recommend at least 3, if not more. Again, these might be different for everyone, but these are my 3 examples:
When using a magazine, or a book to mastrubate, its easy to close it, toss it away, or finish it before you cum. But, with the interent, there is always MORE. How do you deal with this? Close and toss away your laptop, hold the power button and shut it down. Turn it off before it can get to you. As your hand clutches your cock, move your other hand to the power button, and turn it off. Wash you face, cool down, and calm down for a second. Danger averted.
Be effecient. Use whatever space you have to pull yourself back to reality, and remind yourself of your oath. Print out your plan, and put it up on the wall. Pin your oath, or a picture of something to remind you of reality. A gross pitcture can also help, but only pull it when you are mastrubating. Have some ice around, and grab it when touching your penis to help it shrink, or stop altogether. I
sometimes put a board on my chair between my arm rests. That way, I
can't even get to my cock, and it lets me cool down quickly.
I wear clothing when mastrubating to dull the sensitivity, and also so I can't grab my cock easily. I'll have to grind away at it for a while to cum, but when I'm horny, and in denial for a while, even that won't take too long. Have towels to hide your cock quickly while you stare at gross photos to bring yourself down. Remeber, you HAVE TO LIKE it. Enjoy the high of not cumming instead of WANTING to cum. Its here where the real sensations live, as you swim in your own horniness.
