<s>[INST] Hello, I am a 17 year old male and recently I was in the shower and I found a lump on my lower right shaft of the penis. Its skin color and kinda hurts when I touch it. It has gotten smaller over these past couple days. I looked up what It could be and I found lymphocele I think its called. Says it happens after masterbation or sex. I am not sexual active and haven t had sex before. I masterbate about 3-5 times a week. Wondering if you can help me and how to get it to go away or if I need to go see a doctor and get it checked out. [/INST] HelloThanks for query. The lump on shaft of the penis that you have could be either a staphylococcal infection of hair follicle or a Sebaceous cyst.However, this can be confirmed only on clinical examination by a qualified General Surgeon. Take antibiotic like Doxycycline for a week . If it does not subside consult surgeon to confirm the diagnosis. He would be the best judge to decide whether it needs to be removed or not. Chat Doctor.  </s>
