20 yo female with vaginal dryness. used to always be wet, & tested neg. for yeast inf., and am on loloestron to increase estrogen, but still no change?

Vaginal dryness: Usually due to estrogen deficiency, but also should look into sjögren's syndrome (an autoimmune disorder that attacks cells in the body that produce moisture), allergy and cold medications and certain antidepressants, douching, and certainly inadequate stimulation with enough foreplay before sexual intercourse. There are several artificial lubricants that can be used while this is worked out.
