Help, something not right..

Yesterday was the first time I gave someone a BJ and now my throat is really soar and I feel light headed and dizzy and really sick like I'm super hot and sweating and I shake when I get up and my head hurts, all this when it's kinda cool in our house. Idk if it's because I did it for pretty much an hour or if it's because I've never  done it before and the germs from his dick are making me sick orr if it's because I did it after he wore a condom and didn't wash his dick off.
