We wish we had the clear answers to this question. It sounds
as if her HPV was found to be low risk on genetic testing. You cannot assume
you don't have active HPV and may be still capable of infecting a future
partner, but there is no "test" that confirms you do or don't have it when
there are no lesions visible.
You and your future partners are best served by you wearing
a condom at all times with genital contact. It is not a perfect prevention strategy but can help. We think in most cases HPV generally runs its course
in 18-24 months, so that may be the length of time from the end of the
relationship that you need to wait.
Better yet, your future partners should have the HPV vaccine
which does increase immunity to high risk HPV strains and once the vaccine
is approved for men, you should too.
