Another possible scenario is these bumps to be a sebaceous cysts.
They can appear at the vulva or at the vaginal opening as a painless, slow-growing small bumps or lumps that move freely on touch.
Occasionally, infection of sebaceous cysts may occur, with symptoms of tenderness and foul smelling drainage.
There are, also, other possible diagnosis for these bumps.
It is important to get checked by gynecologist!
Best wishes!
