I have very sensitive skin around my pubic area, I can't even use a trimmer to remove hair from the area, the vibration causes unbearable dull pain(discomfort, it doesn't pain exactly). And there are big veins on my penis too, the inner thighs around the bottom of the penis also have slight discomfort. The inner thighs also have dull pain. I have clear urine though at don't experience any pain usually. I have been masturbating once daily for over 5 years now and my age is 20 years.
