Sorry for The spelling im Dutch :) I have masturbated for most of my live, and then is started getung these mild pains in my left testikel, after a few years thy started getting worse, but i did not cut down on masturbation (ones a day) then two years back i had The worst pain ever for about 3 or 4 days.. Then when The pain was gone i Got a echoscopie or a ultrasound check up at The hospitaal.. Result was every thing was ok eksept a very mild swelling behind The left testikel but nothing to worrie about.. Then today i went back to my dockter and checkt my balls by feeling and looking and revieuwing The echoscopie results of befor.. Still my balls lookt healty.. When i masturbate i always pospon The orgasme a couple of hours i think maybe this puts the struin on my left bal, it also pulls up when having a erection.. Its hard to stop masturbating but im trying. Why am i having these pains when my balls are healthy??

Hello dear, Thank you for your contact to Chat Doctor. I read and understand your concern. I am Chat Doctor answering your concern. No, masturbation never causes a pain in testicles. Infact masturbation never causes any harm to anybody. Many people haves many misunderstanding in their mind. Right thing masturbation never causes any harm to anybody. But do not do practice with dirty hand. This may cause infection to you. Epididymitis can cause pain on the balls. So this infection needs to be ruled out. You can practice masturbation as much time as you can practice. There is no harm in it. I will be happy to answer your further concern on bit.ly/ Chat Doctor.
