F oral sex dating

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.The study concludes that people who had one to five oral sex partners in their lifetime had approximately a doubled risk of throat cancer compared with those who never engaged in this activity and those with more than five oral sex partners had a 250 percent increased risk.For conception to take place, sperm from the penis must enter the uterus and fallopian tubes and fertilize the female's egg.In humans, there is no connection between the gastrointestinal system and the reproductive system, and sperm ingested by the woman would be killed and broken down by acids in her stomach and proteins in the small intestine.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.

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.Spitting and/or swallowing of the ejaculatory fluids or giving a pearl necklace may cause different sexual stimulations.Autofellatio is a possible but rare variant; autocunnilingus may also be possible for women with extremely flexible spines.Fellatio may reduce the risk of miscarriages by inducing immunological tolerance in the woman by exposure to the proteins in her partner's semen, a process known as paternal tolerance.While any exposure to a partner's semen appears to decrease a woman's chances for the various immunological disorders that can occur during pregnancy, immunological tolerance could be most quickly established through the oral introduction and gastrointestinal absorption of semen.
