Can I Get HIV, Herpes, STD from Oral Sex? Here's The Risks | anthrotree.info
A wide breadth of behaviors surrounding oral sex may affect the risk of oral HPV infection and of a virus-associated head and neck cancer that can be spread through this route, a new study led by researchers at the Johns Hopkins Kimmel Cancer Center suggests. These findings add nuance to the connection between oral sex and oropharyngeal cancer -- tumors that occur in the mouth and throat -- and could help inform research and public health efforts aimed at preventing this disease. The findings were reported Jan. In the early s, researchers realized that nearly all cervical cancer is caused by the human papillomavirus HPV , a DNA virus from the Papillomaviridae family.
Oral sex , sometimes referred to as oral intercourse , is sexual activity involving the stimulation of the genitalia of a person by another person using the mouth including the lips, tongue, or teeth and the throat. Cunnilingus is oral sex performed on the vulva or vagina , while fellatio is oral sex performed on the penis. Oral sex may be performed as foreplay to incite sexual arousal before other sexual activities such as vaginal or anal intercourse ,   or as an erotic and physically intimate act in its own right. However, the transmission risk for oral sex, especially HIV transmission, is significantly lower than for vaginal or anal sex.
Many people question whether oral sex is really sex. That depends on how you define sex, but one thing is clear—oral sex isn't inherently safe sex. Sexually transmitted infections STIs are definitely a risk, at least if you don't take proper precautions.
