But immature relationship games aside, this is probably not great for your vagina. Edible glitter is sugar-based, so while it might make your fluids taste sweeter in the short term, you're asking for a world of bacterial hurt in the long run. Bacteria love sugar. And when you put a bunch of sugar in your vagina, where lots of naturally bacteria grow, you help them multiply. Stop doing that. That's how you get bacterial vaginosis, where the natural flora in your vagina get off balance. You'll end up with irritation, a lovely fishy discharge, and may require a week's worth of goopy antibiotic cream to put things right again.
