I have many symptoms with few answers. What should I do?

Long story: After my last sexual encounter, I had some very abnormal inflammation in my vulva, particularly in my clitoris. After a couple days of discomfort, I noticed I had some small white/yellowish bumps, which have been diagnosed as fordyce spots. I also got diagnosed with BV and vulvar papillomatosis. I have been treated for the BV and it was cured but the discomfort has not alleviated. Naturally I was worried that perhaps I caught an STD despite practicing safe, protected sex. I have not been sexually active since the irritation began. I have been tested for STDs, thyroid, and hormone imbalances. Everything returns negative. My partner also has severe dry skin on their penis. Could I be missing something? I also have vaginal and anal dryness. It is like the texture changed completely, though the doctor said that was normal. But the opening of my vagina also appears to be more sunken in than it used to look. The lips are also darker. Note: the spots/ papillae are not itchy or painful at all. The irritation is specific to my clit, which seems to house a lot of yeast for some reason. I believe I had some smegma but it was only in that one spot? I believe the irritation was also due to the dryness. I also suffer from extreme dehydration and irritated hair follicles anywhere I have shaved (legs, arms, bikini area, etc...). The irritation of the hair follicles happens regardless if I shave or not.  And yes I tried dieting as well. Nothing seems to help the dehydration and it causes sore throat at times. I know this is a lot but any input or direction would be greatly appreciated. I am confused, the doctors are confused. I just want to feel better again.
