When I was a kid, my church culture taught that using tampons would turn you into a slut, because once you started putting things other than your husband's penis into your vaginal canal, you would not be satisfied with his penis and would continue to voraciously experiment and be ruined for marriage.
It is sad really. These are also the people who teach their young men and boys that they are all uncontrollable rapists who need to be protected by women and girls and even babies always wearing the proper clothing that does not draw any attention to their crotch. (Like pants do.)
There are so many really sick and ignorant fucks out there.
But yeah, in certain religious circles tampons are seen as virginity stealers or the gateway to whoredom so....not super surprised at idiots not wanting to fund women's "luxury items" that they might even believe are more pleasurable than their penis. (And they might even be right on that account).
