I use mine mostly inside the house when instructed to by my wife who is a dominatrix. She inserts it and it stays there untill she tells me it's OK to remove it. The shape of the plug determins is it stays in by itself, (Tapers to a wide spot about 1/3 of the way up.) or pops out (Straight shaft.) The feeling can be erotic at first but after a couple of hours it can become annoying. No they won't make you walk funny or dance better (or worse.) If you can take a big enough plug you'll be dripping cum because it will be banging into your prostate when you move! Start with a smaller plug, use a lubricant, insert slowly and work up to a bigger one until you get used to the feeling. It's just something us perverts like to do![/i]
