(TMI) pimple-like thing down there?

I have a bump on my labia (pretty sure that’s what it’s called although I’m not certain, but it is on the outside on the edge of the flaps, like where the hair is (I am so sorry this is so tmi) it looks like a pimple and after feeling it for what it was or could be, it hurt. 2 minutes later and I’m not in pain, so it’s kinda like when you bother a pimple and it hurts for a sec but then the pain goes away. Is it possible to get pimples down there? What could it be? And should I just leave it alone? I am a virgin so it can’t be anything from sex like an STD, right? (I am 16 if anyone is wondering)
