I stick this in my bum and turn it on and it is all over! Its not too big, but it stretches my hole and keeps it open nicely. I like to use it before sex, to get myself ready for some real action. The vibe part of it is okay. It has a little bullet in it that you can take out. I had some stronger bullets around the house, so sometimes I put one of those in there if I want to go over the top with it. The plug carries the vibrations really well, I can feel it in my thighs.
