Side Effects of Chronic Masterbation?

[curiousgeorge45]

OK... i consider myself an overactive sexual person.  if i dont have sex daily (which i havent for the past 5 years since div) i will masterbate... well this practice has evolved to a 2-4 times a day habit!  my concern beyond the phycological effect is my errection!  i was getting concerned that i was developing ED but wasnt sure what was going on? now in my 5th year of jerking it too much i have a problem getting fully erect and keeing it when i do; pills dont even have the desired effect.... i was reading on an older post that these symptoms could be caused by chronic masterbation.   

my question to this is...
1.  is there any truth to this?

2.  if i stop will my erections return to normal or am i doomed to a limper penis?

thanks
The curious one
