If you have never kissed anyone what are little bumps that appear on your lips time after and they hurt before form?

The little bumps that appear on your lips time after time and hurt before forming are likely cold sores. Cold sores are small, fluid-filled blisters that form on the lips or around the mouth. They are caused by the herpes simplex virus type 1 (HSV-1). These can not form the first you kiss someone.
