What does this look like? Not a vagina pic lol

It's between my inner thigh and outer vagina lip. It was smaller like a pimple but I've noticed it was a little bigger last night. Think I've had it for about 2 months. It does hurt if pressed on. It's about the size of a rock that goes into fish tanks🤷‍♀️ and about half a centimeter protruding out. I do not have insurance but will go if I need to. If I do end up going should I go to a regular doctor or gynecologist? And plz don't start throwing out sexually transmitted diseases. Last time I checked I'm faithful and if my husband isn't just search Florida woman kills husband 😅
