Vagina Sweat?!

I have a problem with my vagina being 'wet'. And what I mean by that is that I can't go a day without my vagina being wet, I don't know if it's because I'm a bigger girl and my vagina and legs are just pushed together or if it's a problem I have. I shower everyday and wash everyday, but I feel so gross and have to change my underwear a few times a day because it's an annoying feeling. Anyone have this as well? Or an cures.
