What Causes Red Bumps And Itching On Labia Minora?

for the past 3 days, my labia minora was really itchy. then yesterday i started feeling some pain in that area. so i took a look and noticed a small red bump (similar to my skin color) on my labia minora, like really close to the edge of it. the bump hurts when i wipe with toilet paper but itches too. it feels hard when I touch it. i'm a virgin. so i don't think it could be an std. what is this bump?
