Panty Vibrators
A panty vibrator sits inside your underwear and stays there while you go about your day, which is exactly what makes it so good. You wear it to dinner, on a walk, wherever, and your partner controls it from their phone without anyone around you having a clue. Most people don't realize how strong the motors have gotten in recent years, brands like Lovense and We-Vibe now pack serious power into something that fits in your palm. They work just as well for solo use as they do for couples play, and the remote-control range on Bluetooth models is basically unlimited if you're using an app.
