<s>[INST] A few days ago, my penis was itching really bad after I got out of the shower. I ve had sexually intercourse with 2 different partners. Also my ballsack was really dry and looked kind of cracked. My penis and ballsack was like that for about 2 days. After those 2 days I noticed that there was a wet spot that smelled fishy on the underside of penis. I washed it in the shower but the next day the smell and the spot was back. I washed it tonight but this time it turned red and looks as if some skin peeled off. The spot is sensitive to touch. I m really scared. Do you know what it is?
