I don’t really need anal training right now because I have been keeping up with anal play, but these are great. I love using the two biggest ones. I usually go for the biggest when I am prepping for another anal play session, but I will sometimes use the medium one for a more relaxed fit. The vibrations are nice and they slide in well. I love the cool feel of the metal, especially when it initially enters my asshole. The vibrations are strong and feel great. The remote makes it mess free once you have the plug inserted, which I love. I used the two biggest ones one after another when using a clit sucker and got off multiple times. The vibrations from the butt plug hit the right spots and feels so amazing.
