I. Whipping Whipping the penis can be done while it is soft or hard. When the penis is in full erection, blood vessels are enlarged so it is important that you are careful in doing this exercise. A ruptured vessel takes a lengthy time to heal and can sometimes interfere with future erections. You can use any type of whip that you so desire as long as you do not use too much force. Striking the penis with the tips of the whip is preferable since any other motion will produce a wrapping effect.
Some companies make a short whip that often times resembles a key chain.
This whip is quite effective in administering pain given it's small size. The plastic tips at the end of the shoelaces can cause great pain to the submissive when they make contact with the skin. This type of whip is also effective because you can design it to a length that you can handle comfortably. Another way to make your own whip is to buy leather shoe laces and braid them together. This makes a short, easily handled whip that will have more weight to it.
