my boyfriend and i has sex last week but an hour or so before we had sex we had oral sex and he cummed. he wiped off his penis and i rinsed my mouth and when we had sex he only had it in for literally 5-10 seconds then we stopped because we didn’t want to continue to have sex without a condom. i haven’t gotten my period yet and i usually get it around this time, should i be worried?
