I understand your concern about these symptoms. While I can't diagnose specific conditions, I want to help you understand some important points:1. Oral symptoms can have many causes, both STD and non-STD related. A white tongue could be due to:- Oral thrush (a fungal infection)- Poor oral hygiene- Dehydration- Normal coating- Various oral conditions2. Some STIs can indeed be transmitted through oral sex, which is why it's important to:- Get tested regularly- Use protection during oral sex- Not rely solely on someone's word about their STI statusThe best course of action would be to:1. Schedule an appointment with a healthcare provider for proper examination2. Get tested for STIs for peace of mind3. Maintain good oral hygiene in the meantimeRemember, only a healthcare professional can properly diagnose your condition through examination and testing. They can provide appropriate treatment if needed.
