As an adult, the only risks for HIV are:
1) having unprotected, penetrative vaginal or anal sex, or
2) sharing IV drug needles with other IV drug users.
You had NO RISK for HIV and you do not need to test. Whatever is causing your sweats has nothing to do with HIV. Oral sex is largely a theoretical risk, so some sites mention it out of an abundance of caution. The truth is that you are more likely to be killed by a vending machine or a hippopotamus than to contract HIV from oral sex.
