Super dry down there

Recently I have been extremely dry when trying to do anything sexual with my boyfriend. These past two times he’s had to resort to Oral because I’m too dry to finger. Today I tried masturbating and even then I was extremely dry. The thing is, I’m very horny but no wetness. It’s kinda ruining the experience for me and making it less fun. It’s so frustrating. I don’t want to resort to using lube so fast, is there any suggestions as to what can be going on? I’m 22 just for reference
