Daniel, PLEASE ask your doctor about oral care products and allergic dermatitis. Even if you aren't allergic to something initially, you can still develop an allergy my doctor assured me (he's a top specialist in one of the best hospitals in my city). I've been seeing a reduction in inflammation, pain, and overall peeling since I eliminated the products about a month ago and started using Protopic twice a day with vaseline in between when I need it. I think in our case the most obvious answer might actually be the truth. I really don't think this is HPV. You can test for it, but if you've never had a cold sore, I really doubt it.
