My gradual change in technique
When I was younger, I learned all on my own the deep pleasure of masturbation. Although in my teens, it was the feelings that made me keep doing it, it was also all about the orgasm. I always jerked to get to the end - sometimes a minute or two was all it took.
But I began reading and developing my technique for masturbation and learned about slowing down and enjoying the journey just as much as the destination. As a result of that, I think, I never had a problem with premature ejaculation in my relationship with my wife.
In recent years, with the help of internet resources, I have learned now about edging and have slowed it down enough that most times I can play without that big urge to cum taking over. And I have learned to ease into it enough that I can most times get the cum to flow or ooze so that the orgasm lasts longer - doesn't shoot as far that way, but for eating and for just watching and enjoying, it's a great change.
I still occaisionally like to just pump it and have it shoot, but I am enjoying masturbation as much now - I think more than ever, although I cum less often. I play a bit just about every day, but I don't cum every day. And I still like a good firm full hand grip, although it's nice to just have it in my hand while chatting or surfing.
