“Is that a one-inch flexible extension in your panties or are you just happy to see me?” If you’re wearing something called the “PantyO,” you can confidently answer that it is the former.

PantyO, a product which we stumbled upon on More‘s website, is a bit of a head scratcher for us. While we’ve debated everything from whether or not Brazilian waxes should still be a thing to the pros and cons of a fur merkin (and we consider ourselves connoisseurs of the ladyparts product market), this one is a first for us.

Basically, PantyO is a blinged out undergarment with a little surprise in the crotch: the aforementioned flexible extension. While not explicitly put there to say, enhance your enjoyment of the vibrations on your subway seat, it definitely has a sexual (yet very unsexy) purpose–Kegels!

In case you don’t know, Kegel exercises–aka the “secret squeeze”–are pelvic floor exercises that women are supposed to be doing to keep their muscles down there strong. Why do you need toned pelvic muslces, you ask? To prevent urinary incontinence (ie peeing on yourself, which is a common problem after pregnancy) and to enhance sexual pleasure for both you and a partner, among other things.

Dayna Garrett, the founder and inventor of PantyO, has five kids and knows a little something about her pelvic floor. We chatted with her about the PantyO to get all the details on how to keep the state of your Virginia in tip top shape.
