@thekingfisher HPV is not herpes. That's HSV.
I was found positive for HPV not long after myself and DP got together. Like you I had been check previously but HPV is not tested for in STI tests. It is only a smear that can check for it.
Fast forward a few years and I was given a nearly all clear Nov 17, waiting on results for smear from Nov 18 (being Ireland its up to 4 blooming months for results) but it seems that the steps I took helped me get rid.
As for telling him, you have too. Men can be carriers, so if things don't work out between ye, and he has another partner he needs to be aware of it. It could have come from either of ye, so do not finger point. Just say that it has been found. Stick to the facts.
If you are looking for things to clear it, take meds to boost your immune system, if you smoke try give it up, my big one was tampons, I was a sporty teenager so have always used them, stopped (for the most part) once I found out I had HPV and things have only improved greatly.
Hope he is understanding because more sexually active people have HPV than are clear from it, this is why they are vaccinating against it now.
