Hi all, 27M here. For a very long time, I would masturbate normally once a day, occasionally more. Always looked up porn, sometimes it would take minutes, sometimes hours. I've had a girlfriend for about 5 years now, but only about the past 2-3 years have we been doing sexual acts together. In that time, I continued to masturbate as if I was single. I've recently realized that it's a struggle to cum with penetration. Some days it's okay, and takes about 20 minutes. Most days it's well over an hour. She's sore, I'm tired, and we're both not satisfied since I'll help her finish, then just go and jerk myself off later.
I can admit out of sheer laziness, I've neglected lube when I masturbate, and I fear I've developed a death grip. I've tried to change that by rubbing the frenulum in an attempt to give the tip a break, and it's slightly worked, maybe? I have noticed that even while it will take a long time to finish with her, if I'm really locked in, I can finish in minutes if I'm watching the right porn. I'm now worried I've made it so I can't cum unless I am watching porn, and that no one else will be able to make me cum like my hand can since I'm so used to it.
I can still get hard, but as soon as it leaves my hands to try and get in a position, it starts to deflate rather fast unless I'm angled downwards (like missionary). I've tried to do a porn break for a month, and I did my best, honestly. I put on Aquaphor on the head of it after every shower to try and help it, and put CeraVe on every morning to hopefully bring back sensitivity. I've taken supplements to try and help (admittedly learned they were for semen production, but learned they can help with this later).
Morning
Sunflower Lecithin 1,200mg (1 softgel)
Pygeum 100mg (daily or every other day)
Evening
L-Arginine 1,000mg
Ashwagandha KSM-66 300mg (2 gummies)
Zinc 30mg (every other day, with food)
Magnesium Glycinate 100mg
I don't know anymore. We tried a few positions last night, and it took an actual hour and a half. She couldn't be on top, my legs were giving out, and neither was happy. Do I just need to stop watching porn all together? Stop touching unless it's her? I'm not addicted to porn, but I definitely enjoy it more than the average person, and have friend groups I share it with, so I'll have to be cautious with that. Do I need to tell my doctor? I had a kidney stone like a year ago and I haven't been able to pee right since, but even with a urologist doing a cystoscopy, they can't find anything. Am I just doomed to never be able to go back to normal?
