First of all, let me say that I commend you for wanting to do the right thing and be honest with this girl! Most guys would probably just have sex and not care who they put at risk! Second, you HAVE to tell her! HPV is very dangerous for women because they say it's the #1 cause of cervical cancer in young women! That said, just sit her down and tell her the truth. After that, it really is up to her if she wants to still see you or not. But if she really likes you a lot, she should be open about this and the two of you can use condoms (which you should be doing anyway) and that may protect her from infection. But condoms are not 100% guaranteed, so she may still be scared to have sex with you. That's just something you have to be prepared to face and if it's not meant for you two to be together, better to find out now than later! Who knows? As common as this virus is, she may have the same thing herself and will be relieved to hear it from you. Lots of people carry this virus and don't even know it. And even when you're symptom free, I think you can still pass it along to others, so you have to be careful! Just talk to her and see how it goes. I wish you the best of luck and please let us all know how things go!
