having shit bacteria in your vagina will cause a yeast infection.
it does yes but pissing after sex helps with preventing that
Pissing has nothing to do with the inside of your vagina, it is two separate holes. Please google.
I know its two seperate holes but they're also literally next to eachother, anything dirty from the dick can enter your urethra and can cause an infection if u don't piss.
I've also cleaned my vagina with water since it helps getting rid of any other left over bacteria but also the vagina is already self cleaning. so unless seonho feels pain in the next couple of days then he's fine
as someone who has gotten an uti from somthing like this before u guys chill anal to pussy is fine as long as seonho pisses after
