For my husband it can hit a few hours after sex or a few days and sometimes not at all. We are trying to keep track, lol. My theory is it depends on his stress levels, and halt.
The worst I had lasted 11 days. But after it I had my best streak. Anyway it really depends on your attitude on the "failing". To me at day 127 it was the real first big streak I was losing, and I felt like shit, like I had no value, I was useless, I tought about leaving the forum. So the chaser lasted 11 days. Last time I lost, I felt like failing was part of my journey. I started the new streak the day after. Attitude makes a big difference
Forget about it. Just don't masturbate. It is simply your withdrawal symptoms resetting to their strongest state since you have just fed your addiction.
