I'm sorry that you and your W are going through this. I believe the current statistics are that something like 50% of all people over 25 or so are carrying at least one strain of HPV. They used to say 25% but have recently increased the statistic. Frankly, it is possible that the infection was not from your infidelity although it is the likely explanation. What is important is where you go from here.
There are some good books on the market about healing from an infidelity - with tips for both of you. You need to make sure that you are scrupulosly honest with your W about your whereabouts, plans etc... You need to make sure that you have answered all the questions that she may have about what happened. You need to be careful about who you associate with. You need to spend time with your W just rebuilding the basics of your relationship. I agree with Nop - some kind of professional assistance is necessary too.
