Yeah, I think it might be a problem. From masturbating the skin on the head of the penis has kind of curled up from stroking it upwards. Some of the feeling on the right side has kind of gone away, doesnt feel as good as it has. I don't think it's good. Is this supposed to happen or what?, I don't check out other guys penis's.
it sounds normal. I don't know if "curling" puts the right image in our minds but I don't think anything wrong is going on. I've dry handed all my life and haven't lost any feeling. It might become less sensitive over time but if you give it a few days rest it'll be back in the game probably even before you are.
