Just to add. I don’t have any sores in my mouth. Just inflamed dry throat. and I see small round red bumps on the back of my tounge and on my throat
I'd say it's unlikely. There are lots of things that cause sore throats, and a dry throat can be caused by so many things - dry air, dust, allergies, etc. Maybe it's time to change a filter in your furnace or something.
Small red sores on your tongue could be apthous ulcers, or canker sores.
You did have unprotected sex, so make sure you are tested for other things, like gonorrhea and chlamydia.
