I am not sure which BIG 3 STD’s you were tested for but sounds like you need a follow up visit to evaluate your symptoms. HPV does not cause fever but can cause small warts in the mouth and throat. This is why the use of protection for both oral, vaginal and anal sex is so important. Your health care provider should be able to discuss protection with you and offer advice on products that offer the best protection. Latex condoms and dental dams made of latex should be used with EVERY sexual encounter.
