Why cant i get wet!!

I’ve always had a hard time getting wet. I think the last time i got wet was the first time i had sex with my bf, and that was 2 years ago. We do do foreplay.... do we need to do it longer? We use lune, but i think its weird that i dont get wet. I read some other posts on here and it seems like others get really wet and im wondering if somethings wrong with me
