Does Masturbation Cause Discomfort In The Penis?

hello doctor, i am 44 years old man, these days i am doing frequent urination, like this, i do urinate, and within 15 mins again feel for urination, but urination is not too much, and i do not feel any pain in my lower abdomen, or in belly, or in backside, just more and more time urinate, i do masturbate, one week 5 or 6 times. and after urinate, sometimes i feel some discomfort in my penis, not feel pain, just discomfort, and within few mins discomfort remove, so does it comes from more masturbation ? or it is prostate problem, please inform me, thank you
