research.  Yes, it is true we can get cancer from licking pussy but mostly white men who tend to contact this kind of dissease.  As for Michale Douglas, his lifestyle was quite preditable and expected in regards to catching cunnilingus cancer.  This guy smoked like fish, and drank like evil while eating out women.  I think his irresponsibility gave him the cancer.  Think about it though, from heavy smokes to heavy consumptions of alcohol then the lack of hygience while being in a drunken stage could very well be the absolute cause.  He should have used candy lube or whipped cream at least.  I wouldn't be surprised if he also ate a lady who just left the bar.

According to the U.S. Centers for Disease Control and Prevention, about 60% of oropharyngeal cancers — cancers of the throat, tonsils and the base of tongue — are related to HPV. It is estimated that every year in the U.S., more than 2,370 new cases of HPV-related oropharyngeal cancers are diagnosed in women and about 9,356 are diagnosed in men; they are most common in white men.
