Hi, thanks for your question. Protected sex is considered safe sex, that is if the condom was on before any contact with vaginal fluids, it remained on during sex and the condom was still on when the penis was withdrawn from the vagina. Unprotected oral sex – in this case – mouth on vulva ( vaginal entrance, labia and clitoris) is considered low risk for most sexually transmitted infections. You can check out the risk chart here https://smartsexresource.com/sites/default/files/Oral-Sex-Table-v3.png It is always recommended to have regular sti testing done so you know your own status and if any symptoms have been missed, then an infection is picked up early and can be treated early. The earliest you can test that would start to reflect the contact you had would be at 2 weeks from the sexual contact and then you might consider testing again to cover sti incubation periods. To find a clinic near you to discuss your concerns in person and to have any testing done, please see this link: https://smartsexresource.com/get-tested/clinic-finder
