Dryness

So Uhmmm...I really need help and advice. My vagina is always dry. And I'm not talking about sex...I mean I get wet during sex but every other time I just don't seem to have that natural lubrication or At least enough of it. My vagina starts to become uncomfortable and I think it's because I'm so dry. Also glow says im supposed to be ovulating but I'm not wet At all... Please help!! What do you think it could be?
