random groin things

Male 18, use ai to summarize it if u don't wanna read all of it, last two days my groin smelled the same it has but I could feel like something, I change underwear and took an shower, I smelled my penis and balls and it smelled good, next thing I exercise that day and I can feel my balls get sweaty and even smelled something while running around, I had problems smelling pee from me when I thought I had kidney stones or problems weeks ago but my bloodwork came out healthy, so I when I sat down I smelled something like odor something that odor but not a wild smell like u know it's a smell but smells odorless🤷‍♂️, I tried getting more wiffs but I didn't smell it anymore and it dosent happen as much and only when I out my head down will I smell some of it but no more after it, I then went on with the day and one morning I went to pee and my penis felt a burning sensation at the bottom, I was confused but i knew that I been masterbaiting and rubs my penis on something but recently my penis started to hurt in that area I rub it or something hurts a little when I do it(low pain), just remembered that happended before all this the day before, yesterday it started itching and I been scratching it, when my kidneys hurt I would feel itchness when I ate something salty, the itch felt like the itch when I shave off my ball hair, but then after it was doing itching my other body parts starts itching, days before I randomly got itches after eating or drinking(some foods), so after the 2 days it was itching my penis starts randomly pain in my penis very low pain sometimes pain at the tip, felt some pain or sensation Cumming but majority of the times I hold it in my penis and then try to splurge it out or pee it out or just hold and then later let go, and at night I used the bathroom and everything went smoothly then some time after my penis hurted, so now I'm making this to see if any doctors can help me figure out what's going on with my groin area
