Symptoms of Thrush
White Tongue
A whitening of the top layer of the tongue or the presence of white spots or patches on the tongue can also be seen with infection or chronic inflammation of the surface of the tongue. Certain oral infections, notably Candida yeast infections (known as oral thrush), are characterized by a white tongue.
You will not have symptoms of a STD the next day. It takes a while for them to show. Additionally, he or you may not have a STD and still get one by doing oral sex. How? You can pass a cold sore to your partner. The best thing to do is have your partner wear a condom during oral sex.
I've done it before and had a sore throat from deep throating... You could've just done it too much. Also, sperm burns my throat. I wouldn't worry about it unless your boyfriend has had other partners.
Yes, your throat could be irritated or you could be getting a cold.
If your boyfriend has not STD's you have nothing to worry about. Has he been tested?
I would recommend seeing your Dr because you're not feeling well. It really does sound like a possible cold to me.
