What does a wart look and feel like?

What does a wart look and feel like? I have a spot that popped up on my labia and I'm not sure what it may be. It's slightly darker than my skin, just a tad bigger than the end of a pen. It's kinda hard. Doesn't hurt or anything, it's just there. I've looked online at warts but I can't really tell if it looks like a wart. It's not an ingrown hair because those have always been sore. Any thought on what it could be? Can't see my doctor right now cause they're closed due to COVID-19.
