You had no risk for HIV. The only risks for HIV transmission are unprotected vaginal or anal sex or sharing IV drug needles. Air and saliva inactivate the virus. You also tested which you did not need to do. Those tests are conclusive and you do not have HIV.
As long as the head of your penis was covered, you had no risk for HIV, gonorrhea, chlamydia, NGU, trich, hpe B or mycoplasma.
Hep C is very rarely sexually transmitted - it's only found in blood - and when it is, it's usually by unprotected anal sex.
Your HIV test is conclusive because you had no risk, as are all your other tests, either because of no risk or the time has passed.
No STD gives you pain in your finger tips or toes (or anywhere on your hands and feet), itchy skin, etc. Some can cause joint pain, but that's rare and you've tested negative. If you didn't give oral sex, you wouldn't have throat pain.
Could this be anxiety or stress? You really can let this go now.
