Super painful insertions

Jess
I'm a virgin and like every virgin I'm told sex hurts. Well for me, any type of insertion is SUPER painful, like swords shooting up there. My boyfriend can't even finger me without pain so intense that I get 100% turned off. I had my gyno try and she could only get up to one knuckle of her pinkie before I needed her to stop. She said arousal and lube helps (both of which we've tried). Anyone else experience this? Advice? My bf is beyond patient to work with me, I just feel like nothing has been helping and I'm ready to have sex soon so this is a major cockblock.
