You had no risk and a test would be a waste of time. If a condom fails it is a large rip down the seam and it hangs in tatters so upside down inspections are unnecessary.
HIV is instantly inactivated in air and also in saliva which means it is effectively dead so it can't infect from touching, external rubbing or oral activities. It doesn't matter if you and they were actively bleeding or had cuts at the time either because the HIV is effectively dead.
Only adult risks are the following:
1. unprotected penetrating vaginal
2. unprotected penetrating anal sex
3. sharing needles that you inject with. Knowing these 3 are all you need to know to protect yourself against HIV. Your situation is a long way from any of these 3.
Even with blood, lactation, cuts, rashes, burns, etc the air or the saliva does not allow inactivated virus to infect from touching, external rubbing or oral activities. The above HIV science is 40 years old and very well established so there is no detail that you can add that will make any of your encounter a risk for HIV. No one in 40 years of HIV history got HIV from the situation you are concerned about so it is unlikely that it will happen in the next 40 of your lifetime either.
You have been given the correct answer to your concerns. You used a condom, which did not break...……..and you WOULD know if it had. As long as the head of your penis was covered at all times, you had absolutely no risk for HIV. The rash, the sore throat, the pains in your legs and arms has nothing to do with HIV. It has everything to do with your severe anxiety. Educating yourself about the basics of HIV and safe sex would go a long way to help you overcome the phobia of HIV. There are many excellent sites on the net to help you learn. I have included a link I hope you will read. It will answer many of your questions and I hope it will help ease your anxiety.

I agree with AnxiousNoMore that if educating yourself about HIV and safe sex doesn't ease your anxiety, therapy would be the logical next step. I see now that you've developed some itching which is freaking you out. Have you ever been diagnosed with allergies? We are at the height of allergy season and all of your symptoms can be related to allergies. We can develop allergies at ANY stage of our lives, so telling me you don't have any could have been true until now. Might want to think about seeing an allergist or at the very least, try taking an OTC antihistamine and see if you get any relief...….that would be a pretty sure sign it's allergies. You HAVE to accept that none of these is related to HIV.
I'm glad you are feeling better about this situation. You NEVER had a risk for HIV since all sex was protected and the condom did not break. I'm sorry that you feel guilty...…..that COULD be the reason behind your physical issues. If those issues continue or get worse, please talk with your doctor. We wish you the best.
