What are the risks of oral sex for men and women ?Is swallowing sperm harmful?

Answer 1

Contrary to popular belief, oral sex is not a completely safe alternative to vaginal or anal sex. Chlamydia, human papillomavirus (HPV), gonorrhea, herpes, hepatitis (multiple strains), and other sexually transmitted diseases (STDs) — including HIV — can be transmitted through oral sex.[14]. However transmission of HIV through fellatio or cunnilingus is relatively rare. Any kind of direct contact with body fluids of a person infected with HIV (the virus that causes AIDS) should be avoided. In 2005, a research study at the College of Malmö in Sweden suggested that performing unprotected oral sex on a person infected with HPV might increase the risk of oral cancer .[15] The risk from most of these types of infection, however, is generally considered far lower than that associated with vaginal or anal sex.

Furthermore, oral sex should be avoided when either partner has wounds or open sores on the genitals or mouth, or bleeding gums in the mouth, or has recently brushed, flossed, undergone dental work, or eaten crunchy foods such as potato chips, all of which can cause small scratches in the lining of the mouth. These wounds, even when they are microscopic, increase the chances of contracting STDs that can be transmitted orally under these conditions. Such contact can also lead to more mundane infections from common bacteria and viruses found in, around and secreted from the genital regions. Because of this, many medical professionals advise the use of condoms in the performance of fellatio (flavoured condoms are available for this purpose) and the use of plastic or latex sheets (dental dams or ordinary plastic wrap) for cunnilingus, although the latter has failed to achieve the same level of widespread use as condoms.
