<s>[INST] Hi I have noticed some small light brown spots on the tip of my penis for a while now , and I was wondering if you could help. I noticed them one day after I had masturbated can you tell me what it is? and if I need medication to make it disappear. thank you [/INST] HelloThanks for query. Brown spots on glans penis are mostly due to infection of glans penis due to contamination while masturbating. You need to take broad spectrum antibiotic like Definite along with anti-inflammatory Chat Doctor. Along with topical antibiotic ointment like Newsprint twice daily. Ensure to wash your genitals with warm water twice daily. Ensure to avoid sexual encounters till it heals up completely. </s>
