How oral sex can give you cancer

“You know the benefits of oral sex: It builds intimacy, helps her orgasm, and feels fantastic. In fact, we doubt any of the 85 percent of adults who have had oral sex at least once with their partner would argue that it’s not pretty damn awesome.
But that doesn’t mean oral sex is risk-free. In fact, it’s one of the most common ways to spread sexually transmitted diseases, like chlamydia, gonorrhea, herpes, and human papillomavirus (HPV), according to the Centers for Disease Control and Prevention (CDC).
And depending on the strain you’re infected with, HPV can raise your risk of cancer—specifically of your oropharynx, or the middle part of your throat.
In fact, the number of people diagnosed with HPV-linked throat cancer is growing: Researchers found the presence of HPV in 21 percent of patients with oropharyngeal cancer before 1990.
After 2000, 65 percent of sampled patients showed HPV, according to a meta-analysis published in Chemical Research in Toxicology.”
