Small, whitehead like bumps ouside vagina hairline?

They are slightly raised an only painful if you touch them. I AM A VIRGIN. I've made out once, and ABSOLUTELY NOTHING ELSE. What could they be? They don't ooze out anything and go away after a few days to a week. I got one, it disappeared, and now im noticing another one. They are actually near my upper, inner thigh. What could these be? Could it be because someone used my razor and then I did?

It could be ingrown hairs, the tend to happen around that area. Ways to prevent ingrown hairs: allow hair to be wet before shaving (approx 5 minutes), exfoliate the area with a gentle exfoliating body scrub, avoid shaving the same area multiple times in one shave, shave in the direction of hair growth, rinse the razor multiple times during the shave to prevent bacteria, use a gentle antibacterial soap externally after shaving.
