<s>[INST] hey because of tight underwear my skinnear penis is become blackish what can i do for removing that blackness hey because of tight underwear my skin(near my penis) is become blackish and i want to my original skin back what can i do for removing that blackness? [/INST] Dear Sameer, Welcome to Healthcaremagic! Skin color of different parts of body is not same & color of penis, scrotum, & nearby skin is usually darker. It is more likely that you noted it now. It is also not possible that color changed due to pressure of tight underwear; still you may use loose underwear. Good luck. </s>
