so i have been having an issue for months and im really embarrassed to talk to my partner about the fact that my vagina doesnt get wet. im turned on, i WANT to do it but sex gets painful for me after a while because im not wet enough, and he constantly uses spit or will try and go down on me repeatedly and nothing works. i dont know what im doing wrong or why i cant get wet and im only 18. we dont just go straight to sex either we always have a while of foreplay and im just so stressed out because sex doesnt even feel good anymore, im so dry and i dont know why. pls help
