<s>[INST] Earlier today I was with my girlfriend, and she gave me a handjob, but my penis scraped against my trousers a few times, and I ended up with a few very tiny cuts on the head of my penis, which bled quite a bit. There may have been some other cuts somewhere. Later in the day, the same thing happened, and we had sex-a few hours later my penis is very swollen-the swelling feels like a bruise. It is swollen on both the sides, and it hurts alot to pull back the foreskin. When I touch the penis head, that hurts too.This has never happened before-Im not particularly worried, Id just like to know if its anything major, and what I could do to get it back to normal, and how quickly it would take effect. Thanks in advance! [/INST] HelloThanks for query .Based on the facts that you have stated I would state that you have developed cracks in glans penis due to dry ,rough ,handling of penis during masturbation and sex. You need to take broad spectrum antibiotic like Cefotaxime along with anti inflammatory drug like Diclofenac twice daily along with topical antibiotic ointment like Neosporin twice daily.Ensure to wash your genitals with warm water twice daily.Ensure to avoid sexual encounters till it heals up completely.Dr.Patil. </s>
