I am a 20 year old female. I have been with the same sexual partner for years. We never had sexual encounters with anyone before us. Usually I get cold sores when I eat acidic foods but I don’t know if it is normal to have these red dots on the tip of my tongue & a tiny red clot inside my upper lip. Can this be herpes, HPV, syphilis or some type of std? They do not hurt or bother me, I have just noticed this.
