A short intro: I'm a 28 year old man. I start masturbating since I was 14. When i was young i used to masturbate 1-2 times a day, than around age 20, progressed to 1 in 5 days or 1 time per week, however, with longer sessions 1-2hr or even 2-3 hr to O, usually with a dry hand. 2 years ago I did manage to stay clean of PMO for 7 months but relapsed at the end. Even though I did watched porn, my main problem was more M, I could not stay out without masturbating. I was so full of energy I could burst. What is strange now is that in the last 2 months i realized such a hard time to have erections even normally. They have become weaker, somedays my penis is completely numb. Even though I still can get it up, however is supper hard, I have to apply much pressure to keep an erection and only with lube (without lube i feel nothing). I don't even have any urge to masturbate or watch porn, its like im completely numb, and during day it feels like my penis is completely numb. I think im suffering from a Death Grip, which has created great panic in my life. Any suggestions? Is it curable? Any story?
