<human>: Could you distill the essence of the text into 1-3 sentences?

I was just tested, results came back positive for HPV (I am vaccinated against the most common strains, but this one is different I guess) 

So, a year ago I went to Europe, I was single at the time and messed around with a few different guys. I was tested immediately upon my return home and the results came back all clear. Within a month after that me and my boyfriend got together (we've been together a little under a year now) We had the talk about STIs, he told me he was tested recently and was clean as well. So we get to it, banging all around town like a pair of bunnies, there is no doubt we both have it.

The problem is this- he WAS tested but not for HPV, because it has no ill effects for men. He *could* have had it. I also found out that I was tested so soon after my return home, it could have not been detectable yet, so I *could* have had it, too. 

I am mortified and scared. How do I broach the subject and tell him? I'm scared he will blame me, he is a great guy and I love him to pieces but I am so scared and I have no way to explain this because it could have come from either of us!
<bot>: No way to know who gave who HPV, but I know about it and need to tell him/explain the confusing situation. Feeling scared and really bummed out.
