Going dry??

I don't understand why Im not as wet as ishould be when I try to hook up with this guy. He turns me on and he does foreplay like eat me out kiss my neck and it feels good but 1. I have never came and we have hooked up (no actual intercourse) like 8 times and then today we were supposed to have amazing sex but I'm literally not wet and I think I made him go soft :-( I'm so embarrassed and dissapointed Bc I'm horny and want dick but when the time comes my body is just like sikeeee. Does anybody have any tips or know what's going on with me?
