I've been to the clinic once, checks and urine tests for all std's came back negitive, i even got a blood test for herpes 3 weeks ago and it came back negitive, doctor said it doesn't look like hiv and im not getting sick. there is no hair where i get these and they are definitly not pimples, you can easily pop pimples and they are normally a little sore. These are not.
Did you make sure that the STD test covered all of the various STD's and STV's? Sometimes they won't test for all of them. It could just be ingrown hairs, or pimples.
