It is the best experience of solo satisfaction I have had. Pour two-three drops of good oil into the condom and wear it onto the erect penis. Now, rub the head between your fingers until you cum. This technique produces ultimate orgasm and and cum is collected inside the condom. Hence you don't worry about the cleaning after the jerking off.
[Webmaster's Note: Using oil with a condom while masturbating is ok, but not if you are using the condom for sex. Oil and oil-based lubricants (like Vaseline) will create tiny holes in the condom. Instead use a water-based lubricant like KY Jelly.]
