After years of masturbating my dick is turning more brown (I'm white, btw) right where I grip my shaft and no where else. I'm assuming this is from years of "toughening" up this skin and the friction abuse on it (I dont use a lot of lube if any). It's not a normal color change, it's definately right where I grip or where I've ripped the skin before and it's healed. Has anyone noticed this with their cock and more to the point, has anyone been able to reverse this discoloration? I think my cock would look a whole lot better all one even shade. Bleaching creme? Dermabrasion? Anyone have any ideas?
