Many people during sex use saliva as means of lubricating the sex organ, but this practice is not healthy as it come with possible infections, as you regularly engage in the act. The bacteria in saliva may cause problem for you too, as it is different with the one in the vagina, and also the bacteria in your saliva and the one in vagina have difference function too. And do not forget that there is enzyme in your saliva which may irritate your sex organ especially vagina. If you are into this practice, I believe you will have a change of mind after reading through this.
Bacteria in saliva
The bacteria in saliva are very different from the bacteria in your vagina,” Saliva also contains digestive enzymes that break down food. When you introduce these bacteria and enzymes into your vagina, the result can upset your vaginal microbiome and leave you susceptible to developing a yeast infection or bacterial vaginosis.
Transmission of Infection by your saliva
“Any STI in the throat or mouth can be transmitted to the genitals through saliva,” In other words, if your partner has an active herpes lesion for example, using their spit to make things slick could leave you with genital herpes.
This scenario happens more than you might think—and it’s the most common way genital herpes is contracted. Even if you don’t see a cold sore on or around their mouth, the virus can still be transmissible.
“Herpes can present with blisters or sores, but it can also present asymptomatically,”.
Other infection that can be transmitted by saliva
Herpes is not the only oral STI you could contract. “Gonorrhea, chlamydia, HPV, syphilis, and trichomoniasis can also all be transmitted to the genitals through saliva,” And like herpes, these infections may not have any symptoms.
“Using saliva as lube provides a perfect storm to alter the vaginal or anal ecosystem enough to trigger one of these infections
Lube to use during sex
I will not mention any one for you, but I would advice that you go to any pharmacy around you and ask for a healthy lubricant for sex. I would suggest you go for water or oil base lube, I think they are safer, than others.
In conclusion, I will say health is wealth maintain it and avoid any risk factor that may jeopardize your health.
