A pimple like bumb appeared a month or so ago, in the place between my anus and vaginal opening. It's not inside, nor does it itch. It appeared a couple days after shaving, so I thought maybe it was a ingrown hair. I've looked up every kind of picture there is to herpes, with no resemblence. As well, as genital warts. I don't wear underwear alot of the time, and usually take baths. It's just one single bump, that doesn't seem to be going away.
