Do you giro the bathroom with your friends in the bathroom with you? Do you poop with them in there? Do u change ur tampon/ pad when they are in there? Ik I do! Theta re your friends they shouldn't care they do the same thing! Unless one of ur friends is a guy then don't do tht!
I'm a male, therefore I don't use tampons. It would be rather strange if me and a male friend were in the bathroom together. Unless, it was an absolutely random encounter.
