The lower HPV incidence rate is due to the fact that the skin on a circumcised penis is thickened due to the constant abrasion. Basically your penis gets covered with a callus. This thicker skin provides an improved barrier compared to the thin and moist skin inside an intact foreskin. But a thicker skin merely lowers the HPV infection rate, as evidenced by plantar warts on people's feet, which are also caused by HPV.

Luckily, as you've said, we already have HPV vaccines, so maybe it's time to stop cutting off pieces from little boys' penises?

That's not really accurate, the foreskin is an ideal area for pathogen development. Almost all STDS are reduced in circumcised populations as well as UTI.
