Chemical burn in vag???

So I had sex with this new "cooling" lube I bought, and it burned like a mf! I'm talking like MAYBE WE SHOULD WASH IT OFF burning. Anyways, I'm uncomfortable, it hurts, we just throw some normal lube on top and try to save the experience. Has anyone else encountered a chemical burn from lubes like this? I'm gonna throw out there that I'm 99% sure my partner is faithful, but for the sake of taking care of myself, I'm starting to wonder if I caught something from him. It's been a few days, and I think I see a leision by my vaginal opening. Maybe I'm just being paranoid??
