Yes but he didn't clarify that he already had HPV before he met her.
But why on earth would he?
He just said he got cancer from oral sex. That really doesn't imply anything about any specific partner at all.
I think it would be fucking weird to assume that a man who has married more than once and has been open about having numerous girlfriends has only had oral sex with his current wife, so why on earth would he need to clarify? 'I got throat cancer from oral sex' clearly doesn't mean 'I am blaming my current partner for giving me HPV and cancer'.
I don't find him a particularly likeable or interesting man, but it blows my mind that people would react to the news 'man has horrible and debilitating cancer and mentions one of the lesser-known causes' by thinking 'he is insulting his wife'.
