I like the idea that it could be something that you could use forever(ish), I have actually seen a discussion regarding keeping one or two of these for every female family member in your "world-altering disaster scenario" bag, however there is literally no way I could use this unless my body changes significantly.

My v****a is pretty much broken. I put in a tampon once (after having my period for 7 years and being sexually active for 3) and cried until I took it back out after giving up an hour later on waiting it out.
And still, doctors insist on telling me that I should "be more careful" or "use lubrication" when I tell them I can't have sex any more due to horrible, fainting-fit-causing pain. Woo.
