im 16, 5ft 7 and 63 kilos. i had sex with someone i dont know very well, and the condom came off during sex. I have no idea whether he actually came. He is australian, 23 and has a long term gf (i did not know at the time). I had a sore throat about 2 weeks after that; it was mild and i had it for a few days, but only at night and in the morning, it just felt really dry like i was thirsty. i had a cold four weeks after, but it was basically just a snotty nose and nothing else, no fever etc, and ive read that congestion in the nose is a sign its not primary hiv. I have no real medical history, no diseases etc.
