I recently had protected sex with a couple females. All at different times but I never used a condom when having oral sex with any of them. About a week ago my tonsils were swollen and there was white spots on them and i thought they were tonsil stones but there werent and now theres a crust that forms around my urethra at least once a day and for the first time today i seen pus come out it. What kind of STI is it or STD?
