sounds like an in grown hair. you are more likely to get ingrown hairs if you shave in this area. if it doesnt go away on its on in a short time or if more appear i would get to you doctor just to be sure.
large redish pimple like bump in pubic hair painfull at first. could it be an std? . it started like a pimple and was painful then grew a bit and got less painful. now it's slightly larger than a pencil eraser red and doesn't hurt. the skin on the surface is peeling a little. it's in the pubic hair not on the penis. what could it be?
