Hey dude, I know this is an old post by now, and maybe you already got the answer you were looking for since then, but just thought I'd jump in really quick. Sounds like you've had some hot hookups though! Anyway, I'm of course no doctor, so I can only speak from my own experience and my own educated guesses/assumptions, but I'd say you're probably pretty low risk based on the fact that even though you've mostly been getting fucked bareback, you only got bred once.
Unless you were bleeding or had any other kind of cuts or abrasions inside when you were getting fucked, I'm pretty sure the risk is really low since there needs to be some exchange of body fluid for you to be at high risk...and then that's also assuming all the guys were poz and also produced enough precum to run the possibility of being infected. So based on all that, I think you're probably pretty safe dude, though you *should*get in the habit of regular testing just so you can be confident what your status is. So, keep on fucking dude lol. Oh and maybe publish details about one of those bareback sessions if you ever have time, I love reading about experiences from other hot dudes
