White patches that rub off leaving a red and/or sore area is most consistent with an oral fungal infection. This can be confirmed by a simple scraping in the doctors office. Often times a presumptive diagnosis will be made based on clinical exam and topical antifungal medications may be prescribed. A feeling of dry mouth is also consistent with this diagnosis.
I strongly urge you to stop "self treating" by scraping the lesions in your mouth and sleeping with candy. Both of these measures are more likely to worsen your condition and potentially increase the risk for developing cavities.
In any case, you should be seen by an Oral and Maxillofacial Surgeon who will take a complete history and after the clinical exam may prescribe a medication or recommend a biopsy.
Any lesion(s) that persist or recur in the oral cavity should be biopsied.
If you still believe that you may be at risk for an infectious or sexually transmitted disease I suggest you see an Infectious Disease Specialist.

Doctor - thank you for the response. Although I know you can't diagnose over the internet does Oral Hairy Leukoplakia go through several significant changes? Meaning whole tongue then part of tongue then no tongue is infected??? I have been told by over a dozen HIV specialists I am negative based on my test results and timing so I don't believe what I am seeing is caused by HIV. Just trying to see if OHL has this kind of up and down history with it? Anything you can share would be helpful as I thought my negative test and reassurances from my Dr's and HIV specialists would help. It seems many Dr's aren't that familiar with OHL.
Thank you and this is my last question.
Typically, Oral Hairy Leukoplakia isn't easily scrapped off and has many different presentations. If you've seen more than 12 HIV specialists and they have all concluded that you don't have HIV, I would guess you don't have it either.
If you want to confirm the diagnosis of either oral candidiasis or OHL, you should see a doctor or oral surgeon that could biopsy the area and have the specimen checked for candida or Epstein-Barr virus (which causes OHL).
