What Causes Pinkish Bumps On Vaginal Lips?

I am a 19 year old girl who has recently discovered small pinkish skin colored bumps on the lips of my vagina. They are just slightly on the inside but barely. They are closer to skin color and not very visible when looking In the mirror, but they feel slightly elevated when touched. They aren t painful but slightly itchy when touched. They are a little clustered but more like in a line down closer to my vaginal opening. I did recently discover them and it s been about two weeks since I had sex (with a new partner) and I don t believe we used a condom
