I had a geographic tongue after i had a non-protected oral sex with a woman that i dont know "Cunnilingus". It has been 10 months and every time i wake up in the morning, i see white lines that go away when i wipe them with the toothbrush leaving red lines behind them. What this could be?

I did HIV test after 6 months and turned to be -ve and did syphilis and it was negative too, and i did hepatitis and it was -ve... please help, what could be the case?

I was treated against Fungus but didnt go away.
