My layperson's understanding is as follows...
Most peoples' immune systems eventually clear the virus by themselves, so that they eventually do not test positive for HPV.
Some people do find the virus persists - not necessarily active, but remaining dormant, having the potential at any time to cause an abnormality (like many viruses do - eg the chickenpox virus is never cleared from the body, but lies dormant for the rest of its host's life, with the potential to cause shingles at some point, but in most people just remaining dormant...). Of those people, some will never actually need any treatment, as no permanent cell abnormality ever arises. Some will get abnormal cell changes, and some of those with untreated abnormal cells will go on to develop cervical cancer and some of those who do not get treated will just have an area of abnormal cells which never actually causes them any relevant health issues whatsoever. Of those who get treatment for abnormal cells, the majority will only ever need one treatment and will never have the problem again - possibly the treatment helping the immune system clear the virus once and for all. Only a small minority of people find they get recurrent problems (well over 90% of people treated only need one treatment).
So, in other words, you are obviously at this moment in time at greater risk of getting cervical cancer than someone without high risk HPV, but this is miles off you being guaranteed to get cancer or even any lasting abnormality in your cervical cells. And using condoms is unlikely to be a huge help, as it is likely you and your dh have already passed all your hpv strains between you - getting another dose of the same thing won't really make a difference, as your immune system can either deal with it, or it can't. And condoms do not, in any event, protect you very efficiently from HPV infection, as this virus is passed on by skin-to-skin contact, rather than by contact with semen, and a condom cannot cover every possible area of infected skin. ie "safe" sex is never totally safe.
So, in other words, it is a horrible shock to find out you have a virus that can cause cancer (I know, as I've tested positive for high risk HPV in the past, too...), but it is not a death sentence!!!!! And looking at it from another perspective, you've probably got all sorts of viruses in your body that are implicated in all sorts of cancers, but it's highly unlikely you'll end up with cancer as a result of any of the other viruses, either. Sometimes, knowledge is just unnecessarily frightening!
