I think I have a friction/rub burn on the underside of my penis. Any creams that can heal it and fade the redness? I have been using Cocoa Butter and Sudocrem, will these work? (I am thinking that Cocoa butter will as its used to fade the appearance and colour of stretch marks)
Use some soap and some water!!
Best way to treat this is natural direct sun light I know it sounds strange but sunlight is the best source of vitamin d, it may be difficult to find a sucluded place to have your penis out in public but if u can it will heal fast and try to keep the area clean as possible not to increase the chance of infection it like any other cut or burn it heals better an faster uncovered with sunlight exposure
