Looking at quality, shape, intesity of experience, fit, material, ease of use and cleaning, the Libida toy testers have agreed on the top 5 best male masturbators:

1. Maven:  Simple, well-constructed, closed-end masturbation sleeve that gets the job done every time.  Made from high quality material with a natural feel.  As stimulating as the more expensive Fleshlight, but easier to handle & clean.  A best selling masturbation sleeve for many years.
Price: $29.95

2. TurboStroker: The highest rated vibrating masturbation sleeve. It pumps, strokes and vibrates.
Price: $59.95

3. Purple Jac-O:  Our testers loved this one for how easy it was to hide and clean; in fact, it looks like a soap dish! Few would guess what this baby is capable of. It conforms to the hand giving the pressure you desire but with a completely different feel on the penis.
Price: $13.95

4. Head Honcho: One of the newer pocket masturbators, this is an inexpensive sleeve with nubs on the inside for extra sensation. Recommended by Sue Johanson.
Price: $21.95

5. Fleshlight: A long time favorite.  Made of soft, realistic Cyberskin to feel just like the real thing.  The removable end cap allows both for easy cleaning and the ability to dial in just the right amount of suction/pressure.
Price: $69.95

About Male Masturbators

Male masturbators come in all shapes and sizes.  They are defined by one single attribute, they all make masturbation more realistic and intense than with just a hand.  Some vibrate and stroke, some have ridges, some are softer or warm to the touch.

1. Simple Sleeves: These sleeves add another dimension to masturbating.  They give the pressure of the hand but the feel of another person. 
Try: Maven, Ultimate Jack-Off or Purple Jac-O.

2. Ridges and Nubs: If you like extra stimulation, one notch up are the sleeves with bumps and ridges on the inside.  These vary the stimulation from smooth to intense. 
Try: Head Honcho, Purple Jac-O and Ultimate Jack-Off Sleeve. 

3. Pumping/Stroking Masturbators: Some male masturbators do most of the work for you with stroking or pumping action. 
Try: Turbo Stroker.

4. Realistic Feel Masturbators: Some sleeves feel so natural and lifelike it is addictive to touch.
Try: Maven or Fleshlight.
