question: Greetings doctor,I am 18 year old boy, uncircumcised. I have little bit of vitiligo. I have stopped consuming all the medicines for it now .I was prone to masturbation and did it pretty much everyday .My penis (glans) looks blue, dry and a bit brown and dark near the meatus(opening). I have very dry foreskin.I was using coconut oil as a remedy. I have a healthy diet but a bit sleep deprived routine due to studies.I have a loss of libido too. I am virgin.
