Okay what can it be if you have a bump on the outside of your vagina where your pubic hair is and it hurts when you push on it or rub against it? (but your not sexually active AT ALL):(

My best guess is a blocked sebaceous gland. Hold a hot compress on the afflicted area until it comes to a head and pops.

It is a blocked sebaceous gland and over time it should get large and burst on its own. Nothing serious. It could also be an ingrown hair.
