Way back in May were some postings about using a
section of bicycle inner tube, cut long enough to
cover your cock, with enough left over to put over the
end of the vacuum cylinder. Got around to trying it and,
believe me, I'm going to do that a lot more. I got a
1.5/2.2 tube. It easily fit over the end of my 1.75"
thick walled cylinder and the inside is easily lubed if you pull
it out of the cylinder. I built a hooked wire for that
purpose. With electric vacuum my cock was very smoothly
sucked up into the bicycle tube.
The advantages are 1. More of the expansion of the cock
goes into length and 2. The donut is less prominant
and, most exciting for me, 3. The inner tube protects
the head of my cock from being bruised when I attach
my heavy duty Swedish massager to the cyclinder with
its spring handles and vibrate my cock inside the
cylinder. Before I would have to stop before reaching
a nice high plateau because the glans would be
bounced off the sides of the inside of the cyclinder
with potential for bruising because the massager is so
powerful. Now I can go as long as I want. By turning
the massager off and on strategically I can keep
myself dancing on the edge for long periods under
vacuum without using my hands at all except for pressing
the switch for the massager off and on. I've been
pumping for over 20 years. This is a new revelation.
A disadvantage is that you can't see your cock directly.
However, you can see its outline pressed against the
inner tube and I cut the inner tube so that the last
half inch of the glans pokes out over the top of the
inner tube (it's the lower part of the glans that
needs protection from the inside of the cyclinder)
and that helps me get a feeling for how things are
going. And, man, what a great feeling when I edge
under vacuum. Woweeee.
