Bumps around vagina? Help

It's something that I noticed months ago.. I thought it was ingrown hairs but when I leave those alone thy just go away. Well I noticed that it wasn't going away and they look like pimples. They're small and skin colored but I can pop them. Is it possible to have zits like around your vagina? Is like in he crease of my thigh close to my vagina where pubic hair grows. If I pop them they go away but I've noticed a new one. It's kind of hard to see but I can feel it with my fingers. Any ideas of what this could be? I have been tested for stds but I came out clean but that hasn't been done in a year and I've only had 1 sexual partner since then that I'm still having sex with. I know he's not sleeping with anyone else because I'm with him constantly.
