You did nothing that would result in getting hiv. Only the head of your penis needs covered during intercourse. So, you were protected. The only risks for HIV are unprotected (yours was protected due to condom not off but still covering your penis head) vaginal or anal sex or sharing IV drug needles. So, you had ZERO risk. And lumps are certainly not a sign of having HIV. You don't have any reason to even test let alone suspect you have HIV. Zero risk
