I hate to be a buzzkill, but all that amazing oral sex you're having might just lead to cancer. There's apparently been a great rise in the number of cases of head and neck cancers, the kind caused by human papillomavirus (HPV) which is spread through everyone's favorite word of Latin origin, cunnilingus.
According to Dr. Greg Hartig, professor of otolaryngology at the University of Wisconsin School of Medicine and Public Health, "It seems like a pretty good link that more sexual activity, particularly oral sex, is associated with increased HPV infection." And according to a study done way back in 2007, having six or more oral sex partners over a lifetime is associated with a 3.4 times higher risk for cancers of the base of the tongue, back of the throat or tonsils. Having twenty-six or more vaginal-sex partners tripled the risk.
