"The viruses in your mask was in your body already and are relatively few to what is still thee. "

Not if it came from someone you were standing next to.

" They don’t reproduce in your mask."

WRONG !
The coronavirus can live on a surgical mask for 7 days, cloth for 2 days, ...

... The researchers behind the new study tested the virus' life span in a 71-degree-Fahrenheit room at 65% relative humidity. After three hours, the virus had disappeared from printing and tissue paper. It took two days for it to leave wood and cloth fabric. ...

And to your last comment:

"The mask reduces the risk of infecting someone else, perhaps older and more vulnerable."

Read some real research.

" ... FACING THE TRUTH Masks really aren’t all that easy. They’re not body armour that stops COVID-19 bullets. And, in the hands of amateurs, they can actually be dangerous. Boston University epidemiologist Assistant Professor Ellie Murray took to Twitter to detail what goes on. “Why might masks for all not work ?” she asks. “Because masks are actually not that easy to use. “Virus droplets aren’t like dust. You don’t have to just stop yourself inhaling them from the air. The virus lands *on* your mask, and if you touch the mask with your hand or face, you can be infected.” Nobel laureate and infectious diseases expert Professor Peter Doherty says the value of widespread mask use has long been disputed. “Depending on how good a mask it is, it can get kind of wet, you know, dribbles, snot, mucus … all those things that are so important, but we don’t regard as being of great value. And if your mask is wet, for instance, and if it did get contaminated, well then maybe you want to drop it down around your neck or something when you’re out in really clear and open air … You’re at more risk from the mask. “So I think they’re very important for healthcare workers who are up close. I’m not so sure they’re that important for the rest of us.”
