I have had ed problems for most of my life.

[K111]

I've had impotence problems most of my life.  For reasons I've never known, as a child I always masturbated in what I later discovered was an unusual way.  Lying on my stomach, I pressed my non-erect penis down onto my fist, squirming around until I had a climax, never allowing my penis to become hard.  I had to press my body down VERY hard against my fist to do this.  I did this several times a day from when I was three until I was 19, when I learned how to do it in the more normal way.  Somewhat later in life I began to suffer with erectile dysfunction, which has become worse as I became older.  My question is: during all those early years, could I have caused some kind of damage (to the veins? to the penis?) which could account for the ED?  I have never heard of anyone who masturbated the way I did all those early years.  Perhaps I am the only one!
