.... I dont get what you're trying to say. HPV is a permanent virus, yes. However, these statistics are just a snapshot of the population with the disease. If you were to take another snapshot of the disease across ages in a few years, the 'bulge' at 20-25 would be shifted (given that the disease does not spread, because otherwise I'm sure it would be more prevalent in the younger populations).
HPV is not good shit. There are lots of strains, and about half of them cause cancer in women. Guys, its our responsibility to find out if we have it or not, because passing it unknowingly to a partner is like spreading AIDS. Ok, maybe not as bad, but you still can give your girlfriend cancer. Get tested, and get your girl to be vaccinated.
