The news that there is a link between oral sex and tonsil cancer is really intriguing...since somebody decided that those vestigal organs that primarily act as sacks to hold dormant infections like strep should be nutured instead of removed at the first opportunity, we now have this threat. Tonsilectomies are safe, quick to recover from and have the side effect of not being a place where you can have cancer if you don't have the place. Also, and more to the point, another reason to have women vaccinated against human pampolona virus. Maybe the sexist twits in Texas who opposed it because not worrying about cervical cancer would make their teenage daughters more sexually promiscuous will get in line with reality since they now have some self-interest here.
Not sure about alternatives -- tongue condoms?
