I'm not a Doc but, I would get tested. Hep C and AIDS are not that easy to catch with protection, but there are other sexually transmitted diseases that can also be exchanged. Using a condom isn't always a guarantee. Alot of these diseases have no symptoms until is often to late. I would think that you would not want to expose a possibility to anyone else. I found out 2 years ago that I had Hep C. I was married at the time and neither of us went outside the marriage. I have since been treated and cured, but have no idea where it came from. Spent alot of time in foreign country's as well. It's always better to get tested, if only for piece of mind.
Be well

well I am no doctor but if you were using protection and the condoms did not break then you are totally safe but in some weird instances oral sex could transmit HIV if you have bleeding gums but the chances of that are extremely low. there really is no need to worry but you could just get checked as a routine thing
