I'm sexually active, but I've never gotten any std. Just now I saw small red shiny bumps in between my upper inner thigh and labia majora. My vagina doesn't itch or burn or hurt at all, but these bumps are just there. Should I be concerned?

Yes you should be concerned. See your doctor immediately.

Of course you should be concerned enough to see your doctor.

Yes, a rash is always a cause for concern. Time to see your doctor.
