Well only a Dr is going to be able to give you a proper diagnosis. Maybe try to find a free clinic or one that works on a sliding scale.
I dont have insurance to see a doc thats also a problem. but ill wait it out a few days. Ive only had it for about 5 days now.
But it doesnt have a head, like a pimple would have.
Pimple maybe? Bumps can be many things often not STD related, you would have to see a Dr.
