I've not done any Penis Enlargement in probably just over 2 years now except for the odd tug and jelq hahaha but that was more 'erotica' if you catch my drift! Anyway touch wood I havent lost a single stat in that time and my girth is still king kong. The only think I have noticed is that I'm not as solid or hard when erect like I was when I was clamping and jelqing .. which is understandable because more blood was going through the penis back than I suppose or was in longer. I would suggest that we do a few jelqs and stretches each month or each week ... nothing fancy, just a few to keep good health. I'm going to get back into it eventually when I buy a new clamp and pump .. will aim for more girth in the future. So to answer your question, yes once gains are cemented and become permanent they usually last but if you havent made them gains permanent than they will be lost. I usually give around 6 months consistent Penis Enlargement to enable me to cement gains and than usually after that it will stay with you. If you notice things shrinking, which we all do at times due to weather, stress and other factors than simply apply a jelq and a hot wrap now and again and that usually does the trick. Much to do with that is warmth and keeping stress levels low.
