Mucous membranes

The reason we are writing specifically about mucous membranes is because they play a central role in the transmission of STIs. It is when two mucous membranes rub against each other, or when a mucous membrane and body fluid meet, that an STI can be transmitted. This applies to all STDs, with syphilis and condyloma being the only exceptions that can also be transmitted via skin-to-skin contact.</span

When it comes to the transmission of STIs, the mucous membranes of the genitals, pharynx and anal cavity are particularly relevant. While it is possible to get bacteria and viruses through the mucous membranes of the eyes and nose, it is not as common. The bodily fluids that can transmit STIs are semen, pre-cum, blood and lubrication. When any of these body fluids come into contact with a mucous membrane, STIs can be transmitted if there are viruses or bacteria in the fluid. Alternatively, if there is bacterium or virus in the mucous membrane.

The sexes and the ass

The cock has mucous membranes inside the urethra. If a person still has a foreskin, viruses and bacteria can also be transmitted through the skin under the foreskin. The mucous membranes of the pussy are located in the urethra, on the inner labia and the walls inside the vagina. The entire inside and walls of the anal cavity are made up of mucous membranes.

The mucous membranes of the cunt and the anal area differ in that the cunt provides lubrication while the anal area has an absorptive capacity. For example, it is possible to take medicine via the anal canal, as the mucous membranes absorb the medicine and distribute it via the blood. This is why HIV is most easily transmitted during anal sex. The mucous membranes of the vagina repel discharge, menstrual bleeding and lubrication. Cunt lubrication acts as the body's own lubricant, making the cunt ready to envelop a cock, fingers or a dildo, for example. While the mucous membranes in the anal area do not create any fluid. This is why it is particularly important to add lubricant when enclosing something with the anal. It will be more comfortable to have sex with lubrication and easier to enclose something.

Transmission

Sexual practices such as oral sex, anal sex and vaginal sex without a condom bring mucous membranes and body fluids into contact with each other. This can then lead to the transmission of an STI if someone is carrying something.

As the different mucous membranes function differently and are of different sizes, the possibility of transmission varies. Transmission is easier via unprotected anal sex than unprotected vaginal sex. The reason for this is that the anal mucosa has an absorbing capacity while the vaginal mucosa repels.

Different sexual practices can be graded according to the ease or difficulty of transmission of an STI, but of course there are several factors that come into play. Such as whether you have a history of another STI, whether you use lubricants or not, whether you alternate between different sexual practices, or whether you have more than one partner.
