You're probably fine, but you could have gonnorea (spelling?)- that could show up as a sore throat. It wouldn't be a bad idea to get tested- there are many free clinics that will help you out and give you condoms as well. The flavored ones are best for oral sex- no nasty latex taste. I give 'em to my kids (I'm a mom of teenagers). Obviously, it's best not to have any kind of sex until you're in a longterm, trusting relationship and have both been tested for all STD's. You can get herpes also from giving oral sex- not trying to terrify you, but you want to learn from this and not repeat the mistake. Don't beat yourself up or freak out- just go, get checked and move on with your life. Now you know that a few minutes of pleasure for a guy or you aren't wort all this stress. Good luck hun- be safe :) .
Ok, one I don't think you have an STD if u did u'd have crazy descusting symptoms if u had any at all. Most people who contract an std don't aquire symptoms. But because you didn't know the guy very well I'd go ahead and get tested just to be safe and to calm your anxiety.
