I don't think you need to change your sexual practice at all.
85% of the population will have this virus at least one time in their life. It is that common. Generally the immune system will clear it. You may go on and get it again. Clear it again. Only a very small percentage of the population do not clear it, only very, very few of them will go to develop a cancer from it.
As Doolittle said, women are who have a positive PAP smear for HPV are not told to abstain.. I have never read any studies /literature that advocates abstinence for those who are positive for HPV. Our medical team certainly never told us to take precautions or abstain.
I for one would not restrict myself to only the population that have known STD's as we know them.
If you are really concerned over this issue talk about it with your Docs. I for one, think it is a non issue.
