Hi my name Rakesh, everything was ok, visited my girlfriend 9 days back, had perfect sex (10-12 times in three days) came back to my place 2-3 days i noticed while masturbating my pennis is not getting hard like it was before and if its gets hard its gets loose soon, and while masturbating feel like sperm didn't come out properly and end up like that, now still have the same condition, i tried to watch porno to test, but dosen't work, i asked some of my friends they say its normal, happend with them same way, i'm little worried please suggest, should i wait for few more days or go to the doctor, please suggest me right. i'm 26 years old, and physically fit, without any health issues
