Side Effects Of Masturbation: Will I Experience Sexual Health Problems?

Hi, my question may seem trivial or rhetorical, but in any case still fashionable among the young and not so young as me… I am a 26 year old man, since I was 11 I masturbate with a certain regularity.. from when I was 20 years old every day… now I have had a girlfriend for about 5 years… despite this I keep masturbating… I wanted to ask you sincerely if this “habit” can bring problems in the future… which impotence or inflammation of the prostate or urethra!… I was also wondering if excessive masturbation brings damage to the corpora cavernosa… such as vein difficulty in holding back the blood!… I know it may seem a naive or stupid question… but for me it’s very important!… thanks.
