I use NuvaRing for birth control and have been doing so for a few years now, and it's a flexible plastic ring which sits inside the vagina for three weeks at a time with no removal during that time. There are some IUDs and more that are left inserted for years. Menstrual cups, an alternative to tampons/pads, can be left in for a recommended max of 12 hours, but I'm sure there are women that use it for far longer without removal and any problems. There was a past where IUDs and tampons (not even just high-absorbency, but the materials used for certain ones...) caused TSS and more, and the risk factor is still kinda there, but nowadays it's almost unheard of. And just keeping something in a vagina doesn't mean it's about to turn into a toxic breeding ground like it did in the past. Not that I support this condom much, but it's probably not unimaginable for a woman to keep it inserted for most of the day if she wishes to, no worries about TSS or whatever else.
