I have a small pimple like bump on the outside of the opening on my vagina. It doesn't hurt only itches slightly. I am only sexually active with my husband of 10 yrs & have been on birth control the whole time. I do not shave in this area however; there is some hair in this area. Can it possibly be an ingrown hair? Can you please give me some idea on what it could be? I noticed it about a month ago & at times it feels as if its gone but when I really check, its still there.. Im pretty concerned... Thanks! :)
