I am currently on 33rd day of NO PMO. So I was just reading an answer on Quora. Which triggers me and I got an erection. Just after reading that answer when I stood up I felt like 4to5 waves of 'something' travelled into my brain. And every wave causes a little pain in my head. So I am not sure if that was dopamine rush. Because I never know how dopamine rush 'physically' feels like even while watching porn. So if anybody knows please tell me. Thank you in advance!
