im 18 & my bf & i have been having sexy for a month or so~ it's been completely fine until 2-3 weeks ago, i got UTI.. i took meds right away and it went away soon enough.. we didn't have sex for a little over a week & we started having sex again about 3 or 4 days ago.. last night we had unprotected sex after using the condom for a few minutes.. & eventually i got dried after the orgasm.. but we continued to have sex and later he used his fingers instead cos he was getting tired.. from after the sex til now, i been getting brown discharge that smells like burning rubber!! could it be signs of the UTI coming back? or....
