On Shabbat afternoon, I had a different kind of urge. Instead of, "I want to act out now," I thought, "I want porn and masturbation back in my life." This poses less immediate danger, but in the long term it could be even more harmful.
I've also noticed an increased sensitivity to life in general. This is quite rewarding, but it includes an increased erotic sensitivity which can tempt me to return to masturbation. Avoiding triggers and, when I do feel desire, noticing and letting it pass, seem like a better approach than trying to get rid of desire entirely.
When I think I want masturbation back in my life, I am imagining masturbation in a resensitized state that comes from abstaining. If I were to give in and start masturbating, I would soon become desensitized again, and the pleasure I crave would disappear. So even from a selfish, hedonistic perspective, returning to masturbation would be misguided.
