From my personal experience, I have not ever seen my girth get smaller from only working length. If we were going only by my own experience....I would say the answer was no. So of course, I cant really answer your question then. Just like I've never seen my length get less when I've made girth gains. Seems like you either gain in one or both directions or you dont. There doesnt seem to be a way to make solidified gains decrease. Thats a 'drawback' to Penis Enlargement I guess, that once you gain...there's no going back. Assuming the gains were solid gains of course. Once the tissues are stretched out, theres not really any way for them to unstretch. I can relate it to a very obese person losing a lot of body fat. They will still have extra, loose skin....unless they have reduction surgery to get rid of the extra skin....after losing so much weight because the skin got so stretched out while they were obese.
Newbies beware! If you dont really want a longer, thicker penis be careful!!
