"No HPV will not wash off and yes it can hang around for many years."
I think you misunderstood. Cancer-causing strains of HPV will of course hang around for many years when they infect a vulnerable area like the cervix. That is why precancerous cells start showing after some years, then years later they get worse, some more years later they turn into cancer-in-situ, etc.
The question was whether HPV strains that cause cancer in the cervix will stay (but not infect, because they can't) on parts of the body like vulva or fingers for years, despite being regularly washed.
I doubt it very much but would be happy to change my mind if you could link to a reputable source that supports you.
"I had one long term partner (my only partner) and hoc resulted in me having to have treatment for pre cancerous cells. The consultant explained the cells were slow growing and I could have had them fir up to ten years before they were picked up. He also explained the majority of the population has hpv in their system but immune systems react differently to it, so for some it is harmless and for others it develops into cancer."
All that is true. That is what happens when HPV is deposited onto the cervix during PIV sex, in people whose immune systems don't clear it (like you and me).
Again, the question was whether it would live on for years on the hand or the nose, for example. I don't think so. We wash, skin cells are regularly renewed, etc. Flu virus can't live on your hand for years so I don't see how HPV can.
