Since HPV can be transmitted through contact of mucosal surfaces and no one wears a barrier on the inside of their mouth I find exclusive association of oral sex and cancer not completely convincing. To me, trying to prevent exposure to HPV is a kind of theater like the security theater at airports.
The effective preventative measure for HPV is like you said vaccination anyway.
