My vagina is ALWAYS dry help!!!

every time i have sex, my boyfriend and i have to use A LOT lube because no matter how wet i am, it doesn’t go in and it hurts for the both of us :/ and it always dries up so quickly. anything to keep the wetness and so we don’t have to keep reapplying?

also, after today my vagina is extremely dry and it feels as if there is no moisture at all... is this normal? this is the first time it has ever happened. i’m way to young to be going through menopause and what is the cause? help! anything to clear things up a little bit would be amazing
