Hello.
A day ago I found a pimple on my lip coincidentally a few days after having oral sex with two different guys, at two different times, who said they were STD/STI free. I had picked the head off out of habit, but there was no oozing or pain in the area before or after i noticed the pimple. It was is only swollen a bit like a regular pimple. Today it formed a scab, but I am still unsure if I have oral herpes or it is just a pimple. Any ideas?
