I've been a pumper for about 6 years. I agree with what Scott said in the video about how good your dick feels inside the tube. The pain issue is mnimal, it's almost like the pulsating hard-as-nails erections I got when I was in my twenties, you know, the boners so hard, you could smash rocks with it!!!
I also think it feels so good to feel my incredibly thicker and longer in my hand after removing it from the tube.
Actually, you're supposed to pump, and remain in the tube, for about 5 minutes. Then, you remove your big cock from the tube and "massage" it for about a minute or two. This gets the blood flowing again and recirculates fresh, oxygenated blood throughout the tissues.
It also feels AWESOME!
Then you can put the tube back on and repeat the session, as desired. Once you're done with your pumping session, your dick will look very impressive, but isn't much good for sex. The benefit you have just attained is that you have increased your dick's capacity to stretch and hold more blood, giving you the potential for long-term growth in length, and, more notably, GIRTH!
Another thing I noticed is, the more sessions you complete, the thicker you get. The problem is, as evidenced in the video, you scrifice hardness for size. That's why Scott had to hold it when attempting to stuff in into his willing girlfriend's wet pussy, it just wasn't stiff enough to be good for fucking.
What I do to avoid that situation is a sort of compromise.
When I want to fuck, with a longer and thicker dick, (just to give my wife a treat), I learned how to avoid the soft-dick problem.
I noticed that after the first pump cycle how big, hard and thick my dick gets. It's noticably longer and thicker, but also IT'S HARD AS A ROCK as well!
So, after the first pump cycle, I can fuck the hell out of my wife and she gets the feeling of having a bigger dick in her...MY BIGGER DICK!!!
She absolutely LOVES it! And the fact it's MY dick, makes it so much more enjoyable for the both of us.
This way we can share in the pumping process and we both reap the benefits of my increased girth and length.
