HIV CANNOT be diagnosed by symptomatology! Diverse symptoms of infection like swollen glands can be caused by THOUSANDS of different microorganisms.
HIV antibidy test will put your mind at ease. Now that you know how you agonize after anything even vauguely unsafe, be careful not to put yourself in the position again. A hot orgasm isn't worth it if it will cause three months' worry.
(I figure 3 months' worry is only worth if for 500 HOT-HOT encounters)
The odds say you are almost certainly NOT infected. Don't worry.
