<s>[INST] Hi, over the past few weeks my foreskin has been getting incredibly dry and flaking a small amount when I am masturbating.  Also, I believe I have a yeast infection as I am not circumcised, I cant pull my foreskin over the head of my penis without immense pain and when I do pull it back I find white build up which also gets very itchy.  What is wrong with me? [/INST] Hello, You may be correct. You should get your circumcision done at the earliest to prevent infections. Therefore I suggest consulting a skin specialist for physical examination, diagnosis and treatment. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr. K.
