Very Fun!
Never used one before but this thing is amazing.  Works like it should and it will work fast. I do not have ED but wanted to add this to the collection and it's a good one to have. It came with a silicone like vagina attachment as well that is so much fun to use. My wife loves using it on me... The 2 rings that comes with it are a bit tight and can almost feel like its going to hurt and get stuck. I did not think I was thick to begin with considering I'm a skinny guy so if you have girth I would be careful or use lots and lots of lube. Other then it being a bit tight it's a fun toy to add.
