Help!!

I have no idea what’s wrong like I have had a few sexual partners this year and I cannot get wet, even when there’s lots of foreplay or if he eats me out or anything, like the second he tries to go inside of me, it’s dry and like yes, I know I can use lube or whatever but I used to flood with wetness and now I can be so turned on and then it happens and I just get so embarrassed but we still do it and figure it out and then after my vagina hurts so bad and I just wanna know if this happens to anyone or if anyone knows how I can get more wet!
