Here’s something new to worry about: oral sex increases one’s risk for throat cancer.
This is related to the widely common human papillomavirus (HPV), the virus that causes a variety of things, from warts to cervical and anal cancers. HPV and its relation to the development of a variety of cancers has been the subject of a lot of study in recent years. It is not yet known whether the “controversial” vaccine known as Gardasil, which prevents HPV infection in women, will prevent oral transmission of HPV.
Thankfully, “’[…]the overwhelming majority of people with an oral HPV infection probably will not get throat cancer', said study author Maura Gillison,” but still! Also thankfully, the study says that while smoking increases one’s risk of throat cancer it does not increase the risk even more when combined with dick sucking.
