My wife just bought this for me unexpectedly. Wow, I have never used one before and it felt like the real thing! The material is nicely smooth and flexible, and it can be used in basically every angle imaginable. You can twist it around yourself in the shower while you are pounding away on it, it is pliable and won't even make you buy dinner! It is easy to clean and discreet. No one would guess what it actually is if they didn't know. Lightweight for travel on trips as well!
If you are a couple I am sure you could hand it over to your partner and let them play with it… the options are endless, really.
