The shape is ideal for beginners. I am not but I wanted to consciously "No one. Small" because I wanted to wear the plug permanently. When standing or walking is also possible without any problems but when sitting much too wide foot pushes extremely unpleasant. On the other hand, the jaws are pressed by the wide feet apart, so that will be granted to the slightly opened sphincter other an interesting sight. Because of the bad wearing comfort when sitting I can not give more than three star yet.
