I want to share the result of an experiment i did on myself. Background: I rebooted recently (took 3 weeks), quite quickly, due to my strong will power and effort on real sex with my new partner (she was very patient with my PIED). I met her on my flatlining period (1 week in) and on the first date we tried having sex and...boom! ED. Tried for few more time over the next week (2 weeks in) and consistent ED. At this point i thought im gonna lose her. After the 18 days mark, (by this time i met her for a week and half) i could finally keep an erection and have sex 3 times that night. Since then i was back to normal, until i did the following a week ago... Experiment: After i got my full erection (including morning wood) back and was able to have sex several times a day and last quite long, i tried this: I watched porn for just 3-5 mins and closed my laptop and walked away. No orgasm, no touching, no erection yet. Quick quit. Later that night i met my gf again. Result: I lost my semi hard feel (being semi hard all the time is how i know im cured and ready for sex any time) on the penis for the rest of the day. The whole day until i met her i was getting no erection even if i touched myself gently. My penis retracted to being super small again. I was already worried. When i was making out with her later that day, i got no erection (she is quite hot, a tattooed blondie with firm everything). She gave me a head and i somewhat got an erection. Inserted in her and after 4-5 mins of sex with semi hard erection i lost my erection. Felt like i will cum anytime, even without erection. Discussion: Its not the orgasm that gives PIED. Its the porn. The release of dopamine in your brain from just viewing is enough to make you go dysfunctional. I did another exp before, where i jerked off clean without porn and only by thinking about her 2 hrs before sex and i still could have solid erection and sex. But after watching a few mins of porn was enough to give me PIED again. Even though i did not edge or even get an erection from watching porn. Conclusion: Porn and its dopamine is the killer. I was breathing pretty heavy while i was even typing down on google for porn. All the rush came right back. It took me another 2 days to heal again somewhat and have sex normally. Thankfully she is in her period now so it will give me some time to get my erection back completely. Advice: Never ever watch porn. If youre not having sex, Jerk off if you really have to. Best is to get a wet dream and let your body take care of the drive and semen production. Only think about yourself and another girl and only about real sex. There should be nothing else in your head other than your partner. And you will be a lion in bed. All the best! Ask away any questions. And also checkout my other post on success story.
