I think you don't really understand biology, human body and how it works, beside understanding what is a pussy and a dick.
It is not just the insertion. If you are worry about vaccinated pussy and the mRNA in her blood,you have to stay away from her if u r a pure blood, including her breath and saliva. Even eating with her during a meal, make sure you dun use her cutlery that she use before , before washing it.
Even sharing a piece of cake ,I will eat half or take half out and then if she touch the cake,I will not touch it anymore due to the fork she use to cut the cake up to eat after putting into her mouth.
