Since you have been sexually active without protection, you should get tested anyway, and you can ask the doc about the symptoms you have.
The mouth spots don't sound concerning - might be normal inflammed taste buds.

Herpes is not common in the pubic hair area, especially a primary outbreak. Sounds like a pimple, or folliculitis. The spots on your tongue are probably inflamed taste buds. The symptoms you describe do not sound STD-related.
Good luck,

Oh yeah.. I didn't know whether this could be STD or not.
