I've had one of these for years and it is still one of my favorite toys. I stuff up my butt and leave it there for hours while I do my daily routine. I can adjust the intensity to my mood or turn it off for while. Its great for prostate stimulation too. The other day I left it in while I went to town on errands. It was a real turn on to stand in the checkout line without anyone knowing that I was having a great sexual experience with it turned up all the way! I don't know if they noticed my funny grin butt WOW!!!
