I spent most of last week being confused/disturbed by Panty O's new kegel panties, which allow you to exercise your vaginal muscles while you wear the underwear. I found this frightening, but then I received a press release for the Magic Banana. Never heard of it? I hadn't either. It's a flexible accessory for "strengthening your inner magical muscles." I'm not going to get anymore detailed, but I think you should watch the instructional video. Just do it. It uses the phrase "in the smiling position." So it's marketed as a kegel exerciser that is supposed to help you achieve multiple orgasms.
The Magic Banana led me down a kegel wormhole. Pun intended. Let me warn you, most kegel exercise products are pastel and look like Medieval torture devices. But if your vagina's been slacking off, you might want to check out some of the products available to work the lazy girl out.
