Is Needing Lube for Sex Normal/Okay?

I need to use lube in order to have sex; I've been this way since I started having sex 2 1/2 years ago. If I don't use lube, there's no way it can happen, or it CAN happen, but it's not enjoyable for me AT ALL. I thought at first it might be because I wasn't turned on enough, but the guy I'm with now is more than capable of turning me on 😏 I can orgasm and still not be wet enough to not use lube! I know I'm pretty tight, but still... is it bad that my body doesn't provide enough natural lubrication no matter how turned on I am?
