Katie,
Yes. I have the burning like that too. I have about 3 guesses as to what it
could be (since like you, no one can tell me what's going on.)
1. Allergy to the toilet paper
2. Menopause (just as you said, thinning, dryness, yada yada)
3. Yeast infection
My best guess is #2, MENOPAUSE:woohoo:
Once I asked my gyno what the little red prickly spots were on my stomach and he said "There's a word for that. It's called O-L-D!"

I love my gyno....
Glad there was no blood in your urine. I like the photo by the way.
Take care,
Ro
