The bumps on back of my tongue seems lill bigeer doesn't hurt or anything not sure if it was always like that. Vaginal sex only, std? / hiv?

Probably normal. More than likely circumvallate papillae, large bumps on the tongue that are normal. (top line of the picture).
See a dentist. Most likely what you are seeing are your taste buds and they usually do not hurt. See your dentist for confirmation.
