Some people complain that the thickness of the plastic dulls sensation.A report issued in September 2005 by the National Center for Health Statistics was the basis of an article in the September 26, 2005 issue of Time magazine.The Centers for Disease Control and Prevention (CDC) stated in 2009: "Studies indicate that oral sex is commonly practiced by sexually active male-female and same-gender couples of various ages, including adolescents." Any sexual exchange of bodily fluids with a person infected with HIV, the virus that causes AIDS, poses a risk of infection.Risk of STI infection, however, is generally considered significantly lower for oral sex than for vaginal or anal sex, with HIV transmission considered the lowest risk with regard to oral sex.Plastic wrap may also be used as a barrier during oral sex, but there exists no conclusive scientific research regarding how effective it may or may not be at preventing disease transmission.Certain kinds of plastic wrap are manufactured to be microwaveable and are designed to have pores that open when heated, but there also exists no scientific research on what effect, if any, this has on disease transmission when used during oral sex.The breakdown products are then absorbed as a negligible quantity of nutrients.However, there is a potential risk of pregnancy if semen comes in contact with the vaginal area in some way, such as semen in the ejaculate finding its way onto fingers, hands, or other body parts, which then comes in contact with the vaginal area.
but using a real dental dam is seen as preferable; this is because real dental dams cover a larger area, avoid accidents caused by "slipping" outside the covered area, and avoid the risk that makeshift versions may be accidentally damaged or poked with the scissors during the cutting procedure.Links have been reported between oral sex and oral cancer with human papillomavirus (HPV)-infected people.In 2005, a research study at Malmö University's Faculty of Odontology suggested that performing unprotected oral sex on a person infected with HPV might increase the risk of oral cancer.The study found that 36 percent of the cancer patients had HPV compared to only 1 percent of the healthy control group.
Another study in The New England Journal of Medicine suggests a correlation between oral sex and throat cancer.
It is believed that this is due to the transmission of HPV, a virus that has been implicated in the majority of cervical cancers and which has been detected in throat cancer tissue in numerous studies.
