There are a multitude of waterproof massagers currently on the market, and they all have different applications. So the first thing you will want to decide, is what sort of stimulation are you looking for and where you want to use the massager.

Waterproof massagers can make your bubble bath or your showering a very memorable experience that you will want to repeat over and over again. 

There are some massagers that are able to stimulate both the clitoris and the internal g-spot, at the same time.

You’ll want to make sure you have some sort of traction such as a mat on the floor of the shower or the tub, because these little devices will make you squirm.

Other devices are made for complete insertion and have the controls within easily reach so you can adjust your stimulation levels while the device is still in place. Again, you will want to have some sort of shower mat or something in place.

The saving grace of these little devices is that they do eventually run out of power, otherwise you might miss work or even bedtime.

If you are not familiar with any of these devices, you may want to visit an adult store that supplies them, there you can get a better idea of what you might want. If that is too close and personal for you, you can also talk to experts online that will be able to help you figure out what will satisfy your needs.
