In the presence of tiny sores and bleeding gums, oral sex can lead to the transmission of HIV infection. This was recalled by the dentist Kapil Khurana.
In an interview with the Lenta.ru portal, a well-known dentist recommended in case of chronic gum problems not to engage in oral sex with casual partners. It is well known that some STDs, including the deadly HIV infection, are transmitted through blood. The highest risk occurs during oral sex, since it is the most traumatic, and here the probability of microcracks that appear during friction is the highest. Oral sex in this regard is considered the least dangerous, since HIV virions cannot exist in saliva. However, when performing oral sex, HIV can enter the body through the smallest injuries in the oral cavity.
Oral sex will soon become the main cause of cancer
This threatens the transmission of not only HIV infection, but also syphilis, various hepatitis, herpes, and gastrointestinal parasites. So if you suffer from bleeding gums or know that you have received some even the smallest injuries of the oral cavity, it is better to refrain from oral sex completely. Especially when having sex with a random partner, the reliability of which you are not sure.
Oral sex is better than a stamp in the passport
The dentist emphasized that over 600 types of microorganisms can be in the oral cavity of a person, and on the surface of the teeth their number is even higher – sometimes it reaches several thousand. Any cuts or scratches in the mouth, sores on the lips and skin injuries in this regard are an increased risk. It is better not to practice oral sex, but to visit a dentist and wait for complete healing. (READ MORE)
