AnyOtherDay

I just want to ask a question to make sure everything is ok. I have a girlfriend and we use ky nearly every time we have sex. I can finger her for hours and she will still be dry. I can eat her out and indirectly use my spit as a sort of lube, but only on a few occasions has she been naturally wet. I think the really weird part is that when she comes there is a wet spot covering half the bed...

Now I am fairly new to the sex thing, only being 22, but the other few girls I slept with were way easier to get wet and stayed wet throughout sex. So I was wondering if her dryness is something I should worry about, and I was wondering if any of you girls will give me tips on making her wet.
