I gave my boyfriend oral sex the other day. That night I had a sore throat and it hurt to swallow. I have little red dots in a horizontal pattern just before the uvula in my throat. They are sort of on the roof of my mouth but back further. ? He claimed that he had a scratchy throat before that ever happened. I'm afraid it is an STD. I don't know much about STDs at all and I am seeking help.. Am I just freaking out or is it really something I need to be worried about. I have not taken any tests.
