Let me see if I can help...
Your best bet is to hang a weight from it each night before bed for 20-60 minutes. This will increase the extensibility of the corpus spongiosum prior to nocturnal erections experienced while you sleep which will, in turn, stretch the tissues internally.
Start with light dumbbells and work up to heavy kettlebells (up to 40 kg.) over several weeks increasing time as tolerated. The kettlebells provide a more effective pull because of their thick handles and unique shape (See Mahler and Tsatsuoline, 2003). The Russians have used them for many decades, so you know it must be an effective treatment.
Based on the current literature and some Russian translations from the late 60's and early 70's (See Sportivny Press) acquired after the fall of the Berlin Wall, there does appear to be a limit of increase based on initial size and tissue type. The best indication of maximum size acquisition appears to be related to color believe it or not.
The proper sequence appears to be a color change from red, to dark red, to purple (indigo per the literature), and then black. Once black is attained, you've reached maximum length. Continuing beyond the final stages as indicated may cause accidental amputation which so far has been shown to be irreverseable except for several cases (See Bobbit et. al. 1996).
Keep in mind as with any training method, there are inherent risks. The primary risks appears to be an associated loss of girth as length increases and complete loss of function. However, this stage has been shown to be an effective measure in such cases of selecting an appropriate width of pasta for protein + carbohydrate meals.
As a side note, once you attain the ability to withstand the 40 Kg. kettlebell you may want to consider contacting Jim Rose for future employment.
Hope that helps.
