The virus spreads by respiratory droplets that are released when a person infected with the virus coughs, sneezes, or talks. These drops can be inhaled or dropped into the mouth or nose of a nearby person. Coming into contact with a person's saliva through kissing or other sexual activities could expose them to the virus. You are not contagious because of that episode of Covid.
But we know that it's possible to get Covid more than once, so you should behave as you would if you never had it. Despite the fact that there is a perception that oral sex is safer, it's not worth being too literal. Not exchanging saliva will reduce the risk of contracting or spreading Covid, but it will not eliminate the risk. Masks are definitely the new condoms, in terms of sex.
The same warnings apply, as Draeger says. They touch each other a lot when people are in that situation, not just when the condom is on. Experts in the fields of etiquette and sexual health agree that expecting people to wear masks while having sex is unrealistic. It is much safer than doing anything else with a fully vaccinated person, meaning it is still not impossible to transmit the virus, but it is 80-97% less likely, depending on the vaccine you have been vaccinated.
Overall, the findings suggest that the mouth plays a greater role than previously thought in the infection and transmission of COVID-19. Researchers suggest that virus-laden saliva, when ingested or inhaled, can spread the virus to the throat, lungs, or digestive system. Knowing this raises hope that a better understanding of how SARS-CoV-2 infects the mouth could help point out new ways to prevent the spread of this devastating virus. COVID-19 can also be spread through feces (poop). Therefore, it is possible to get COVID-19 from sexual activities that could expose you to fecal matter, such as unprotected oral sex in the anus or placing a penis or sex toy in the mouth after being in a person's anus.
