Oral Sex Linked to Cancer

So according to a recent study, the number of oral sex partners you have is positively correlated with your chance of getting oropharnyx cancer. I'm not sure how I feel about this. But here's a quote from the source:

"The latest data suggest that 64% of oropharynx cancers - growing in the middle part of the throat - in the United States are caused by HPV, which is more than tobacco causes, said Maura Gillison of Ohio State University. And as the number of partners on whom you have performed oral sex goes up, the risk of oropharnyx cancer goes up."

Something to keep in mind, that's for sure!
