Suggest Remedy For Intense Itching, Dry And Swollen Testicles

What s up doc, so recently I had unprotected sex with my girlfriend, we have no diseases or STDS. We had sex 4 times in five hours, however I didn t ejaculate 3/4 times because I didn t have a condom. I also didn t shower afterwards until the next night. About a day and a half ago, I developed an itch on my ball sack, today after I aggressively itched my balls around noon, I noticed it was swollen. I think that my balls are dried out and itchy because I didn t shower after all the sex until the following day, and the swelling is from excessive itching, but if this sounds like anything else, or could be bad I would like to know what is wrong and what I should do. I read online that lotion and baby powder work so I tried them out. Right now I m itch free but still swollen looking ballsack skin.
