I've heard on string vibrators, but I'm not sure what they are exactly. Can somebody explain what makes them different from normal vibrators and how they work?
String vibrators, also named strap-on vibrators, normally have a string or strap that makes it possible for them to be worn around the waist or hips. They're frequently used for hands-free stimulus during intimacy.
They're great for partners who want to discover new sensations each other. The string or strap helps keep the vibrator in place throughout use, which can ameliorate happiness and intimacy.
I've used a string vibrator before, and it can be a fun way to spice factors up in the bedroom. They come in a variety of shapes and sizes, so it's on finding one that works best for you and your friend.
