a guy went down on me, and the next day on the outside of my lady parts is a little red with tiny bumps... what std's show up the day after?
Most Helpful Opinion
The day after is REALLY fast ( lice maybe? Phthiriasis or Pediculosis pubis link ) and "tiny bumps"? I don't know if they bite, they probably do under the "right circumstances". In any case lice are annoying but if it's that, your life is not really in danger.
Remember, I'm NOT a doctor! (and condoms don't help against lice. Shaving does, if its that!)
