This. Protects against strains you don't have, reduces the spreading. We (male that have sex with females, and haven't been vaccinated) are a huge infection vector.

My doctors have generally refused vaccinating me for years (Male/43yo), but finally a new (female) doctor told me it's a good idea. I'm not in a risk group, so I have to pay for the vaccine: Gardasil 9, 3 doses, 3 months away of each other, ~€200 each, although studies say that 2 doses might be enough.

In reality, you can pay to a private doctor so they write you a prescription, but I feel more validated if my doctor says it's OK :)
