Dryness

So I am normally decently wet when aroused. For the past month or so I just haven't been able to get wet like a girl should be able to. I'll be turned on and even get to the point of orgasming but there's no personal lubricant with it. My boyfriend and I can usually tolerate it decently because there's enough in the beginning to get things going and then once I orgasm he'll go until it either becomes too uncomfortable for either of us or he orgasms. However it seems that the problem is getting worse as tonight I was unable to get wet at all. We tried at first and then pretty much just gave up and cuddled. Has this happened to anyone? What are your thoughts? What helped? We don't usually have lube because we generally lose it between our sexy time or it's never around when the time comes. I seriously feel inadequate as a woman.
