I asked the same question (why boys don’t get it) and the only info I could find said just that it had not been tested on boys. Interestingly, boys CAN get cancer from HPV as well, altho it’s not as common. One would think that if something really worked, and the goal was to get rid of the disease they would have targeted both boys and girls and tested the drug for both.

Men can get testicular cancer as well as throat cancer from HPV.
