Panic not my female friends because nothing is going to get lost up there. But if you do forget about that tampon then you may develop Toxic Shock Syndrome, in which case, go to your doctor and don't forget about it next time. Your vagina isn't like a never ending vessel, so anything that you can put up there, you can also get back out - although you may need the help of a surgeon for some things... But seriously, your vagina is essentially a dead end or a cul-de-sac, so nothing is going to get lost. And remember that babies come out of there, so you don't need to worry about anything getting stuck. This information should not be seen as a challenge in any way, shape or form.
