<s>[INST] My boy friend has a lump that appears under the skin its kinda soft on the botttom side of his penis and sometimes he also gets small clusters of tiny hard bumps on top of skin he says hes been tested and its not an STD ... What could it be how do I bring it up without hurting his feelings ? [/INST] Hi! Good morning. I am Chat Doctor answering your query. The history suggests that he might be having multiple sebaceous cysts of the skin which is a benign but annoying condition. I would advise you to counsel him to see a dermatologist or a general surgeon in your area who after a clinical examination and related investigations could solve your boyfriends problem. I hope this information would help you in discussing with your family physician/treating doctor in further management of your boyfriends' problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. I wish you an early recovery. Chat Doctor. </s>
