What Causes White Bumps On The Vaginal Lips?

Hi, Im 19. I got out the shower like a week ago and before I got out I felt inside my lips towards the entering of my vagina and I felt like a bumpy like surface. I got out looked in a mirror and the surface was white like. Like tiny white bumps but they dont bother me at all. It doesnt burn when I pee or anything. Can you help me to what it is and how to make it go away?? Thanks
