Ok to cut a long story short, I had two random sexual encounters in Ethiopia but they were all protected sex throughout. I haven't tested for Hiv yet but I'm worried about the effectiveness of the condoms used. I didn't test them after the encounters and I don't know if that's necessary. I developed chills nearly four weeks after the first encounter and do not know of it was ars or just any other infection not related. How worried should I be? Are condoms really effective against HIV? I have a girlfriend I don't want to harm her!
