I used to overtrain all the time. I would not do PE for a few days, then I’d overtrain for one day and get no results and would be turtling all day.
I believe the key is consistency on a daily basis and moderate intensity is what has helped me. Also, I have tend to stop watching porn, as someone else said, it can put stress on the penis if you do this right after a workout. I may do it before a workout for 10 minutes, but that’s it.
My theory is if you start out with a “light” routine and work your way up, that is when you will grow. If you go “all-out” to begin with, your body will try to adapt and then you REALLY have to go “all-out” again for any growth.
Like me, when I was a newbie, I tried going all out because I thought I’d get gains quicker. I found out the hard way this isn’t so.
This is why I believe newbies can gain so easily if they do their routine right. Their penis is unconditioned and even if their routine is light, their penis isn’t used to it so it grows. As they start adding a few minutes more there and a few minutes there, it keeps growing because it takes time to adapt.
Just my thoughts :)
