Vaginal bumps

Ok, so I've studied up on different types of bumps that can accur on a vagina but I feel like I'm getting no where. They don't itch or irritate me at all. I didn't even know they where there until acouple of months ago. They look like tiny, soft, bubbles. But they don't pop or burst. They are all surrounding the outside of the entrance of my vagina. Please help!!
