100% true. I still go through flatline whenever I decide to switch on to hardmode. In my current hardmode streak, I experienced 1-2 weeks flatline. I almost always had morning erections when I was addicted and still experienced crippling PIED so if someone has lost morning wood as well while addicted, then that's indeed a very alarming sign. Actually, I could even get random erections during the day while thinking of porn. All these random erections made me think that I am perhaps some sex god and would be having sex almost daily with my woman after marriage just like I masturbate. How things turned out was quite the opposite though. And now I am exploring this semen retention/sexual transmutation aspect of nofap as well so yeah. Thankfully, my wife is apprx 6 months pregnant so I can sort of get away with this for a while. What really confuses me is that if this semen retention thing is for real, how would I able to sexually satisfy my wife along with practicing retention??? I am exploring all of this but first things first. I need to experience this retention/transmutation thing myself as to whether such a thing even exists or not?
