I don't think you need to be worried, but I do think you should see a doctor. You've had a lot happen in a short period of time.
Your doctor may be able to prescribe something that will help you heal faster than polysporin.
Also, hand sanitizer never should be used on the genitals, and won't work to prevent an STD infection. Once you're infected, you're infected.
You should also have a doctor take a look at your testicle to make sure that's okay, too.
Let us know what happens, and I hope you feel better soon.
