But he is too embarassed to go to anyone other than me because he trusts me alot. He masturbates frequently and does it without lube. After a while he has noticded that the top of the head is dry and chaffed looking and it has even left a discoloration that is different from the natural skin tone of it. Everytime he masturbates he uses lotion now, but after it dries it leaves an ashy mark over the discolored skin. I wanted to know if there was some type of stuff that you guys suggest he could buy to help him or a website with doctors that are well knowledged in this topic.
