This Wartenburg wheel is great for sensation play. I used it during a self-play b d s m session, and it was perfect for that. It doesn’t hurt or stab you like some can. It just gives you a nice sensation on your skin. I have some other Wartenburg wheels, and one of mine has 5 wheels and feels as sharp as nails, so this gives me a good variety of sensation play. It’s good for lighter scenes, self b d s m scenes and beginners to BDSM or sensation play, or people who aren’t into intense pain or blood play.
