I am a 21 year old women and I have been STD tested before, and I am sexually active... I occasionally get 1-2 under the skin white bumps that are about a mm in size on the outside of my "lips"/ where my legs touch my genitalia... They do pop and a small white seed will come out. I've looked up herpes and many other std's and this is so minimal in comparison that I definitely do not think it is anything of that sort... any suggestions?
