Hi D,
To know for sure, see a Urologist.
Are you cut or uncut (circumcised or uncircumsided)?
If you are uncut you should be very sensitive. Being circumcised removes a lot of sensitivity intended by Nature which is why I would never have any of my Sons circumcised. They are all Natural and always will be as far as I am concerned.
You may be stroking it too hard and furious too. Are you ever gentle with it? Do you ever take time and relax and enjoy or do you just do it to get it over with? How hard a grip do you place on it? Do you use lubrication and what kind and how much? Small amounts of Vaseline work best because it does not become so lubricated you take away any friction that will be necessary for success. You need to cause a certain amount of friction and heat from that friction and maintain "feel" and to be variant in your methods - sometimes hard and furious and sometimes gentle and slow. How big are you? Do you utilize all of you or do you just focus on the head and leave the rest of your Penis alone?
One time a day should not be "too" much. How long do you take? Seriously. How long from start to finish do you figure you are taking? Are you "violent" with it? Brutal? Remember nothing can withstand over abuse. A certain amount of "Sexual abuse" is fine. Are you doing this to yourself or are you having someone masturbate you? What methods are they using? Do you tell them what to do and how to do it WHILE this is being done - is there communication that is HONEST between you?
Take Care, John H.
