Egg vibrators have been around for a long time acquiring a huge following for several reasons. They are the most versatile available. For example, Use them alone for internal vaginal stimulation by inserting them like a tampon. Hold them against your clitoris for direct clitoral stimulation. Insert them into a hollowed out dildo for occasional penetration with vibration. Use in conjunction with a butt plug by holding up against the base of the plug. Also, Egg Vibrators have been known to deliver very powerful vibrations. Being delivered from a much smaller area than most vibes, the egg's vibrations are extremely focused, hence more powerful. They come in a variety of colors and have been the most discreet vibrator for a very long time. So, the vibrating egg has obtained some very loyal users over the years.
