This is because sperm can remain in the semen and the reproductive system for several months following the procedure, and it can take up to 90 days or more for all the remaining sperm to clear out despite several ejaculations.

Got mine back in November, just did the semen test - still have dead sperm in there. No live ones, but they recommend continuing alternative birth control until NO sperm are present. I have FAR exceeded the suggested 30 cannon fires. Upon finding the dead sperm, they advised that I retest in a few weeks and increase my ejaculations in the meantime. Guess I'm going to twice a day.

30 in 90 days... man I'd be a different person. Microdosing no-fap. Can't even imagine it as someone who ...tends to things... at minimum twice a day.
I understand there would be tenderness and you really wouldn't want to irritate it for several days. But by week 1 I'd be looking at the least tugging options to get the job done. I remember I once went camping with family. Didn't clean the pipes for like 5 days. The night I got home I took the longest shower of any young mans life. Probably clogged a main drain somewhere. Didn't consume anything but Gatorade and Protien bars for the next 12 hours. It was an event. Doing that to my body for three months.. I'd be fucked, I'd be changed. I would probably have healthier relationships and less ruthless associates. As it is I can only hang with people who live on their own knife's edge. Maybe it's internalized bullying, maybe it's unresolved anger, maybe it's a fight in the guys head between what he know is real and what he wants to believe. But all my friends are fucked in the head too. Probably not from fap addition though. I don't rightly know.
