I'm glad you wore a condom. That's great, always do that. It protects you. You never had a risk for HIV from your exposure. As long as the head of your penis was covered, you are protected! The only ways that adults get HIV is from unprotected vaginal or anal penetrating intercourse or sharing IV drug needles. The transmission only takes place inside the body. Air inactivates the virus. Some contact std's are easier to transmit. You can ask about that on the std forum here at medhelp but you do not have to worry about hiv from your exposure.
Hello. This may surprise you a bit but the HIV is not as "strong" as people think. What I mean is that the only way you can get HIV is when your blood or other body fluids get in contact with hers. And I don't mean just a droplet, it has literally to be a LOT of blood in direct contact. So, the only way of acquiring HIV from another person is by direct intercourse, needle sharing and blood transfusions. Just to keep you calmed, statistics say that when you accidentally pinch yourself with a bloody needle, the probability of being infected after 1 ml of blood is just of 0.3%. The HCV is a lot more infectious, so, don't worry, you have ZERO probability of being infected with HIV, take a deep breath and enjoy your sexual life....with responsability.
