Spent a few weeks seeing if: 'Breast Pumps' did anything... I believe they stretch that area, but not in a good way. Women have fat in that area that responds to such things, but men do not... So all Breast Pumps are really doing is giving you a continual love bite on your tits, which might result in some growth but only from stretching the skin and possible damage (scar-tissue) building up underneath and swelling to cause apparent: 'growth', which will be short-lived as the body tries to repair. That's just my view though. I personally never had any growth using the Breast Pumps... Just sore tits. I'd also be concerned about the constant tugging in the chest area due to the heart being in that area. Sigh... The quest for tits continue! - But the journey is part of the fun!
