Can’t get wet

My bf and I have been together 2 years. The first 2-3 months the sex was PHENOMENAL! I mean all the time, multiple orgasms from sex, oral, and fingering. And we were both so into it. Then after that the sex is still amazing, but for some reason I’m not getting wet anymore 😞 He thought it was because I wasn’t attracted to him anymore which is absurd. Then he thought maybe I had low estrogen or something. Well I got that checked out and it’s fine. So he’s saying it’s that I’m “in my head” too much. We have found a lube that we both like but sex just hasn’t been the same. He doesn’t like having to use the lube, guess its a man thing. I don’t know what else to do. After we get going the waterworks come on just fine, it’s just getting started that we have the issue with. Suggestions? It’s taken a toll on our sex life and I want it back!
