I use a yellow latex dish washing glove for a sleeve on my
X-40. I get the largest size glove and cut the fingers off, so that the hand part creates a latex sleeve all the way to where the thumb part is. I turn it inside out( yellow part facing the inside of the
Bathmate) and use a rubber band to secure it to the outside of the
Bathmate. I use a great lube that I got form pumptoys.com called GLYDE that is not only waterproof, but makes the skin feel wonderful. I hope this helps someone that is having
Bathmate comfort issues.
