Masturbation problems 22 year old male

Hi there, just came across this site and can't find anyone with an exact problem elsewhere, so any help appreciated.

I'm 22 male, I don't masturbate often. When I'm talking to my girlfriend online, we'll masturbate together and I know I'm in the mood, I have precum, no problems with erection etc, but when I masturbate, I can't really get close to orgasm and can't ejaculate at all. Precum is the most I have. And sometimes afterwards, I get stomach, abdominal and testicular pain/ache. Any reasons why this is?

Thanks

when you have precum without ejaculate , it means youe prostat work and it doesnt exit from your body , and its harmful , masterbating (masturbating) is not a natural action ( specially when you are far from your partner ) , I advise you stop it , it could have a bad efect on your future sex life ,
hope the best .

Hi Andy, having a full seminal orgasm while sitting in a chair could be affected.  Your pushing on the tubes where the sperm comes out. Next time try it laying down in a pron position and see if its better.
