Yes, flavored lubricants that contain sugar or glycerin are very common causes of yeast infections. You should look out for those as well as other artificial and harmful ingredients if you are really sensitive. I personally have been able to use sugary lubes and even real chocolate syrup (a one time thing to never try again!) down stairs with no issue, but it's really bad for your cooter.

I would be careful if you must try them. Like I said I'm not that sensitive, but I do well with Wet's flavored lube. I love theirs! However, there are natural flavored lubes as well. If you aren't sensitive to these ingredients like glycerin, then I would say try with caution. I LOVE Jelique's products. They're all really fun flavored products. They have flavored everything and those never give me problems.

If you're worried, but want to try them. Just do so with caution. Wash really well afterward and don't use exceedingly. One question you could ask yourself that will help is: do soaps like your typical drug store body washes irritate you down there or give you UTI's or yeast infections? If not ever, then you may be okay to use (sparingly!) products that do contain the glycerin and such. There are flavored ones that are safer though.

And if it does so happen you wake up the next morning with what feels like the beginnings of a yeast infection, you can get rid of it immediately, naturally for less than a dollar. Seriously.
