I don't recommend the following products and they are not safe. For a detailed list of these products, see my Sex Power page. The list is not exhaustive. You can read about a variety of ways to use them here.
There is a new type of vibrator for anal use (which I use, and recommend). This new vibrator has a more powerful and wider range than the old type. It is more accurate and less painful than the older type. It has a high-intensity, powerful pulse for anal use and it is compatible with both male and female condoms. Read more about the new Vibratex Sleeve and Vibratex Intense for anal here. For anal play, the new Tenga Super Power Vibrator is a favorite. It is a very large, powerful vibrator that feels amazing inside your butt. Tenga is a pioneer in the world of vibrating anal toys. Tenga is also the inventor of the Super Power. The Super Power is a revolutionary product. It contains a rechargeable battery that will last for 2 hours. If you like to feel your own orgasm, the Super Power vibrator will give you a great workout. When it's not in use, it has a simple and discreet button that makes it easy to keep it inside. There are multiple attachments to add your own vibrator.
