Yup, completely normal. Usually, when you're really juicy down there, it's because you're ovulating. The mucus thins up to let sperm through so you can get pregnant easier.
Of course, being dehydrated can make the dryness worse, and those with ichthyosis are constantly dealing with dehydration.
Get yourself some astro-glide. Works very nicely.
