Prostate pain during reboot

Hi all!

I have been absolutely loving nofap, I have been on and off it for nearly half a year now! My best streak being 54 days!
Just wondering if anyone else experiences this; every time during a reboot around day 14-25 I get this weird sorta prostate pain. No idea why but after a relapse it goes away? For some background info, I am 18 years old and into the gym a fair bit! I do eat lots of red meat and all that, I have a semi stressful job 5days/week and nofap seems to give me the motivation to push through the day! It would be fine if not for this damn pain, it comes on for maybe 5 seconds at most (after urination usually) I have no other symptoms no other symptoms just this random ache!

Please any suggestions or tips would be more then helpful!

Thanks,
