I have HPV-how do I tell my bf?


I got a call from my dr yesterday that she found HPV during my routine pap, and I need a biopsy in a few weeks. I had a clean pap in November before I slept with my bf (I have only slept with him, I was a virgin). I don’t know how to tell him, and I have to suggest he contact his past relationships to let them know they should be tested. Besides being worried about this for my own sake, I am not looking forward to this conversation. I don’t want to sound accusatory, because I know there is no test for HPV in men nor is there a vaccine (which I got but it doesn’t cover all strains). I’m feeling very ashamed anyway. Can anyone give me some advice?
