Thank you guys, things are clear now...
Answering the question of Pete McVries, I used to masturbate to porn between 2 through 3 times a day... until I started to get flat line...
And then, I went to the doctors, started to make several exams, not only to investigate the cause of my ED, but a lot of other things caused by an overwelming stress I got into by then...
Then I discovered the book of gary wilson that clarified a lot these things to me... and I stopped watching porn since august this year.
I do not watch porn anymore... but sometimes I was relapsing because of the girls almost naked in Facebook and Instagram... So, I decided to delete these apps from my cell, last week...
I still haven't been able to go through a whole month without masturbating... but I do it, maybe five times a month... I think it's a progress, but I am using medicine to have erection... I went to the urologist and he told me to use a medicine for two months so that I would return to normal...
I'm using it, and I feel normal... I'm feeling great... [Moderator's note: explicit, graphic comment deleted].
