I got Gardasil this past year myself, I just barely made it under the upper age limit they have right now. I had no side effects other than it kind of "burned" for a little bit after the shot. Well worth it in my opinion, even in a monogamous relationship, considering the other option of possibly dying of cancer from a virus most *everyone* has, or can get even without sleeping with other people.
I'm not in favor of all vaccines willy-nilly, but that is one my kids will get (when I have them).
