If you want to get an
idea of what pumping is like before spending money on expensive
equipmentbuild your own homemade penis pump!
The easiest homemade
penis pump to build uses an aquarium gravel cleaner. Look for
the two-inch cylinder size with a flat end. These can be found
at any pet supply store.
Use some electrical
tape (the black tape about ½ inch wide) and carefully start wrapping
it around the bottom of the cylinder until you have about a 1/8-inch
or thicker ring. Try to have the tape layer extend very slightly
beyond the end of the tube.
Next cut several one-inch
lengths and tape from the outside of the cylinder over the ring
layer to the inside of the cylinder. Do this all the around the
tube slightly overlapping each new piece of tape over the last
one. Repeat this several times until there is a pad of tape close
to ¼ inch thick. This will 
create a comfort ring so that the cylinder will not cut into your
skin as you pump!
Apply vacuum by sucking
air out of the attached hose. Go slowly following all the rules
of safe pumping already discussed. Be very careful it is easy
to apply too much pressure and injure yourself.
Also these aquarium
tubes are much more fragile than a real pumping cylinder and could
shatter causing injury. If you decide pumping is something you
would like to do invest in the proper equipment.
