I have that microwavable heating pad and its been effective for months and the other day for some reason it burned about () that much of my skin. Its a small cut or burn but its healing now. I was wondering that if it develops into a scar would that prevent me from gaining more girth or can a scar be stretched out too while your peing? I hope it doesnt develop into a scar. Its on the undershaft of my penis and i have been keeping it moist with healing ointment. Is it true that if you keep it moist that it will heal again? Seems like its a minor burn.
