Jarod Johansen's Ball Stretching Guide

Obtain the Measurements:

On a ruler, measure the string length it takes to go once around the top of the testicles, then pull the string so it is tight but does not slip higher on the scrotal sack. It is very important that the sack be loose and free hanging for this measurement. Please see the example pictures on the photo plate available below for proper placement of the string and correct tightness.

There have been many questions regarding exact placement of the string when measuring for stainless steel weights. To answer questions and clear confusion, the author puts forth several images of exact string placement when measuring. The author will not give a dialogue on each picture but rather will let them speak for themselves. Included is a picture of a hanging sack before measurement. The ruler picture shows placement of the string when measuring. The following photo plate demonstrates the measurement method. Click here to view the photo plate.

After several practice placements, begin measuring and writing down the results. Have a piece of paper and a pen handy on the bathroom sink and write down the measurement. Take a total of 5 measurements writing each measurement down after it is taken on paper. Note that no measurements are needed from around the "equator" of the two testicles. Be CERTAIN that a repeat of placement of the string is done from scratch so that any measurement errors can be eliminated by taking the average. Also, if only one of the measurements is way off, eliminate that measurement. It is a measuring error and shouldn't be in the average calculation. In this case, add up all 4 remaining measurements and divide by 4. Additional measurements are fine and encouraged to be certain the correct measurement is obtained.

Calculate the Inside Diameter:

1. Determine the average. Add up all 5 measurements together, and then divide this answer by 5. This is variable A. PLEASE remember if you measure in inches, you need to convert to millimeters at some point. This conversion might as well happen right now. This conversion calculator will convert the inches measurement to millimeters.

2. Calculate your comfort size range: From now on we are using millimeters. The size range concept is easier to grasp and is a revision of the previous usage of tightness multipliers. Now, everyone will calculate in one standardized way and calculate a comfort size range from tightest to loosest. Knowing your size range should eliminate quite a bit of confusion when it comes to selecting pre-sized split collar weights. Now, simply select the split collar size that is closest to your size judging from your personal tightness preference based on your range.

Multiply Variable A by 0.74. This is Variable B

Multiply Variable A by 0.80. This is Variable C

What we have just done is create a size range using the following chart. We only need to know the smallest and loosest sizes and the intermediate sizes need not be calculated.

3. Calculate inside diameters for the comfort range: (Formula is D=C/3.14) Divide Variable B by 3.14, this is Variable D. Divide Variable C by 3.14, this is Variable E.

4. Final Results for Sizes with the Comfort Range Defined: The best chance of a fantastic stretching experience will occur with a weight size at or anywhere between these two poles.

AN EXAMPLE OF THE CALCULATION PROCESS FOLLOWS:

Variable A average measurement is 6.0 inches.

Convert 6.0 inches to millimeters: 152.4 mm (Google "inches convert mm")

Calculations:

Comfort Range:

152.4 x 0.74 = 112.8mm = Variable B

152.4 x 0.80 = 121.9mm = Variable C

Find inside diameters:

112.8/3.14 = 35.9mm = Variable D

121.9mm/3.14 = 38.8mm = Variable E

Final Results for Sizes with the Range Defined:

35.9mm <------------------------------------------------------------------------->38.8mm

Tightest Recommended

Loosest Recommended

For the purpose of accuracy and ordering the right size the first time, the author welcomes an email that lists your measurements, calculations and determined inside diameter calculation. Please list the calculations as they appear in the above example. The author also suggests a picture of the scrotal sack hanging loose and relaxed for comparison with the calculations. The author may give approval for a correct size to order, however, a measuring error or larger than average testicles can throw off the calculations. The true inside diameter may be a slight variation of the author's approved inside diameter. If this happens, please do not harass the author but rather be assured that the incorrect weight size can be placed above another weight higher up on the scrotal hang in complete comfort. Please do NOT worry; the weight can always be used. In the extreme case that the weight is unusable or if there is a desire to sell the weight and try again with a different size, please email the author since he is familiar with many men who desire to purchase weights of all sizes.

PLEASE NOTE that some users with very large testicles have had their best success using a tightness multiplier of 0.85 through to 0.90. For guys with very large testicles, simply replace the numbers 0.85 and 0.90 with the above method's 0.74 and 0.80 in the calculations yielding Variables B & C. The majority of users the author has had contact with have had excellent results using a tightness multiplier of 0.74 through 0.80.

Now that the measurement is known, the next step is to make your selection of weight to fit. Take into consideration internal diameters, external diameters, and weight (ounces or grams). There are quick websites available to convert weight (type in Google "ounces conversion grams") and to convert length (in Google type "inches conversion mm"). Many ball weight websites are in metric and English systems, however, be aware that there are a few mistakes in the conversions so it is best to do your own set of calculation conversions. Use the one you are most comfortable with, metric or English. Some sites have their own metric/English conversion calculators.

In general, most ball weights are basically the same with standard shapes and standard sizes. However, the prices are somewhat different from site to site. A stainless or surgical steel weight is recommended rather than a chrome plated or iron material. The stainless and surgical steel can be left on indefinitely and can get wet with sweat or in the bath and shower or even in the swimming pool. On chrome stretchers, the chrome plating may wear through to the solid brass interior. The copper in the brass turns green when exposed to moisture (such as sweat) turning the scrotum green. Once the copper comes through, the weight should be thrown away.

The shape of metal ball weights is usually standardized although secretleather.com uses the higher quality double machined circular type, as opposed to the more often found elliptical shape which is cheaper and quicker to make, but less consistent in sizing. Metal ball weights are a slice of stainless steel, of several thicknesses. The center of the steel is honed out to create an internal hole in the slice of steel. The internal diameters of this hole vary as described above. After the machine shop is finished with carving out enough steel to fit the standardized weights, the inside edges of the weight need to be rounded out. Fresh from the machine shop, these edges are razor sharp! After the edges are smooth, the surface of the weight is highly polished, or in some cases, polished to a brushed appearance. Some stretchers are coated with titanium to create a rainbow spectrum of colors when held to the light, for a more festive appearance.

When wearing metal weights, smaller lengths are by far the most comfortable. This includes the sizes of ½ inch to 1 inch in length. The reason, for example, is that having 4 half inch weights on the hang, compared to a solid 2 inch weight, makes for easy movement of the weights laterally size to side. This means that the weights can hang in contour to the scrotal sack and in contour to the surrounding clothing material. The movement, shifting, and bending at the "joints" between the ½ inch weights behaves similarly to the spinal column and individual vertebrae movement. A series of these smaller length weights, especially the WMC™ weight, exist in perfect comfort-so comfortable that they are usually out of mind and out of thought as they are worn for extended periods, yes, even 24/7 for several months. They only need to be removed for cleaning, as discussed in the chapter on "Wear and Care of Leather and Metal Stretchers"..

After the order and product has been delivered, the wearer is free to wear the weight continually for an indefinite amount of time. Some men may find that after a period of time, the smooth edge corner of the internal hole may start to "dig" into the scrotal skin and create a red ring of irritation. This is called a "pressure point". A 16 ounce weight can form pressure points around the top of the testicles after an extended time in the same position such as while at work or while sleeping. Most pressure points are not terribly bothersome. When they occur, readjustment of the weight and scrotum becomes necessary. Often, lifting the weight up higher on the sack or turning the weight 90 degrees would takes the pressure off the compressed skin at the pressure point and transfer the pressure to a different position on the scrotum. Using a weight that allows the user to wear all day and all night is far better than using a heavier weight that causes painful pressure points after only a few hours and must be taken off.

If pressure points become a problem, a completely round band of surgical steel (as opposed to the 90 degree edge of steel on standard ball weights) is available. This type of weight is called a WMC ™ weight (formerly known as a Wedding Ring ©) and is available only from secretleather.com. The WMC ™ weight has a design that takes the stress and pressure and distributes it the entire way around the scrotum where it sits above the testicles and not at a single point as with standard weights. This ring totally eliminates pressure points, and allows for heavier weights to be added with the ring at the bottom evenly distributing the weight around the scrotum. The WMC ™ weight is so comfortable that the weights positioned above it on the sack cannot be felt. Pressure points do not occur using the WMC ™ weight. Standard weights, with their 90 degree cut and square corners are comfortable for a few hours, however their pressure point pain can be felt after several hours of wear. The standard weight was not designed for long term wear - it's only useful as a short term sexual toy for the man for a sexual session lasting up to a few hours. The WMC with it's completely round shape is designed for long term wear. It's shape brings comfort for long term wear. Days, weeks, months, they are all entirely comfortable with the WMC. The company, Secret Leather, is an excellent company based in London, and has excellent customer service and a fast order turn around in addition to an exceptionally high quality product. A WMC ™ weight should be owned and used by everyone who uses metal ball weights to stretch the scrotum. Ideally, a WMC ™ weight should be directly above the testicles, followed by a heavier weight or even an aggressive length ball stretcher, and followed by another wedding ring positioned on top. This will prevent pressure points from occurring on the scrotum around the testicles as well as around the top formation of the scrotum against the body. The WMC ™ weight is exceptionally high in quality but is also somewhat expensive, especially to United States residents (currency exchange rates are not in our favor against the British Pound), but they are worth the money in exchange for the pain and time it takes to reposition standard weights on the scrotum. Of course, be aware of WMC knock-offs. The genuine WMC has the two halves that fit perfectly together with the two surfaces of the weight joining together perfectly in a steel-to-steel seal. The WMC knock-off surfaces do not meet completely together, meaning there are small but open spaces when the weight halves are brought together. Scrotal skin gets pushed into the cracks and gets pinched, causing pain and irritation.

Some users have found that using stainless steel shaft collars, intended for industrial applications, can be substituted for an actual ball weight. The problem with these however is, that the edges/corners of these objects are generally sharper and not radiussed as in dedicated ball weights such as those available from secretleather.com. For certain, in using an industrial shaft collar for weight, two WMC ™ weights should be used on each end to prevent painful and intense circular pressure points. The good thing about the industrial steel shaft collars is that they are seldom more expensive than $14.00. If this route is chosen, pay attention to the materials used to make the shaft collar. Cold rolled stainless steel is good, but anything iron should be avoided. Some users have found that plastic shaft collars are useful as spacers only when additional weight is not needed. The author believes that 5 pounds of weight is probably the maximum weight that should be attempted. This equates to roughly 5 - 5 ½ inches of stainless steel. If the stretch is longer than 3 inches and the user wants to stretch as well as use gravitational force to pull down on the scrotum, then these plastic shaft collars could be used. Ideally, a WMC ™ weight should be placed between the plastic collar and any flesh it may otherwise touch.

Ball Stretching using metal weights is probably the fastest method available with regard to with scrotal growth. At one time the author believed that metal weights only did their stretching when they were in a vertical standing position. The author has now taken the time to feel and examine the pressures when wearing metal weights. He has come to the conclusion that metal weights are always exerting a pressure on the scrotal sack. When lying down on the back they hang straight down at right angles to the legs, when lying on one's side they are either tucked between the legs and hanging off the back thigh or lying forward and stretched out toward the penis. If enough metal weights are placed on the full hang they can even take on the same role as a leather stretcher; pushing both up and down on the scrotal sack. The weights are always at work, but can be temporarily disabled by wearing tight underwear.

One final note in this section is a reminder that the users of metal weights should be conscious of secured destinations. These include airports, secured schools and government buildings where metal detection is a standard security protocol. Simply leave the weights at home or pack them in your suitcase for further wear at your destination.
