Too dry to function!

Sometimes, even when I’m really horny, I just can’t get wet! Or I will but it’ll remain inside my vagina and my clit and labia will remain dry. Or while having sex, I’ll become dry!

I’ll have sex and after my labia get so swollen and it hurts. After that, I’ll be completely dry for days!!

What do I do? (Lube is great but I want my own wetness!!)
