I am a 23 year old sexually active women and while I was examining my vulva, I noticed many white bumps on my labia minor. They appear to be in rows on both sides of the opening on my vagina and extend back to the area between my vagina and anus. They are painless to touch and seem to be more visible (some of them only visible) when I pull the skin around them tight. I do not believe they are herpes or genital warts because they are painless, smooth and i had the Gardasil shot before any sexual activity. Are they possibly large fordyce spots or blocked sweat glands? Or are the really herpes or genital warts? Any help is appreciated!
