So I'm 37-years-old and I have been PMO since I was 15. I've been clean the last 45 days, which is my longest streak. My fear, though, is that in my case the damage may be irreversible. Ever since I remember, I masturbated in a soft penis. I could get semi-hard watching porn, but my masturbation was always in soft penis. Have I done an irreversible damage to my body? I can still get morning wood, less often lately which led me to believe that I'm in a flatline, but I'm afraid that this could last forever. Any advice will be greatly appreciated.
