Is my friend masturbating too much?

You can believe me or not that it's a friend. I don't car. but he says he gets these sores on the head of his and these little pin-sized sores bleed. a little bit. I told him that he's probably doing it too much. also he's not cirsized and doesn't use lotion. I kep telling him that with all these things adding up, it's a miracle he still has it! lol anyway, he says I'm not an expert and what do I know and all this and whatever, so I told him to use yahoo answers and he had me use mine because he doesn't want people to know his name. his name is Dan. lol and he does ist nearly every day. I laughed at him and he's all mad now. XDD
