Thank you TicoTexan and redwitch! I figured that the seal was starting to fail. Did a little further research and people have said that as the seal gets older it will do one of 2 things, or both. The toilet will start leaking a little cause the seal is not tight, or the seal will get too tight and cause the tower to get sucked into the opening a little tighter thus taking some additional effort to flush.
Well, off to Home Depot or Lowes for some shopping
Thanks again to all who replied !!
