pimple on inner labia

Hi.
For the past 5 months or so, I have had 3 pimples on different places on my right inner labia. At first it was the inner wall of the opening, then on the edge of the labia and the latest one is on the head of it right next to the clitoris. I called my gynecologist and she said it was a stress pimple that comes and goes due to PMS and stress before my periods. I am a virgin, so we always rule out STD's.

Is there any other possibility to this? I popped the first two, but the 3rd is skin colored and doesn't seem to have any yellow mucus contained in it. I am also very clean about that area.

Any medical names I research?
Thanks!

Maybe try posting in women's health, this is a STD forum and since you are a virgin it is not a STD. I can't be much more help on this one.
