Outer vagina (I think) pain, really hurts please help

I feel this painful type of tugging/tight/sharp pain that I think might be from somewhere in between or around the flaps. I'm a virgin so I don't think it's inside I've never felt anything inside but possibly like the entrance? Anyway, I felt it around 3 or so days ago but at first I thought it was only when my underwear would cause friction when I moved in certain ways. I decided to go underwear free tonight & I felt it again when I spread my legs. I tried to see what would sooth so I squeezed my vagina together I guess, like I pushed the 2 "camel" parts together & once it released back I felt the pain a lot more. It hurts when I'm on my side completely legs bent & start to open my legs with one leg, so kind of making like a v or right angle. It really hurts when I do that & when it releases after I push together. When I spread my legs it feels like something sharp is there. I am a virgin I don't even use tampons so idk if it feels like something sharp is going inside but on Sunday (it's late Thursday night/early Friday morning now) my boyfriend came over & what we usually do is grind on each other but with our underwear on. I'm not sure if it might've been friction from that & having my underwear on after too. What can I do to soothe? Will it go away? What is it? It hurts a lot, any help is appreciated
