Drying up

Hey ladies!

I'm planning on talking with my Dr. about this, but I figured I'd check here first. So, I'm 25 years old and for the last two years or so I've been drying up super quickly during sex. I'm honestly not sure if I'm orgasming or whatever, but I get super into it when we start having sex then I seem to like hit a climactic point and all my "moisture" is suddenly gone. I'm left yearning for more sex, but my body is like nah. It still feels good and I want to continue having sex, but I'm dry. I feel awful cause my boyfriend usually isn't finished when I am. I get that we can use lubes and other things, but I'm mostly wondering if something's wrong with me. Thanks in advance for any help!
