It’s ok to do this during an erection, but this is not a requirement.
It is better if the sound has a tapered shape, the sphincter needs some time to get enlarged. Since it is smooth muscle, it’s comparable to butt fucking where the sphincter also needs some time to adapt.
And no, I just put the sound in, slowly, let the sphincter accommodate, take it out and insert the next with a slightly larger diameter.
If you do it slowly and with appropriate size I found in the beginning that it can be quite painful and even produce systemic reactions (sweating, nausea). Now, that I know the system, I go a little slower as needed. Like so it feels quite nice and I can understand that some folks do that for sexual stimulation. The best feeling is at the inner sphincter at the level of the prostate.

Personally I’d be interested in trying this for urethra/glans enlargement and possibly CS enlargement too, which ttt mentioned he’s noticed a change in. I think it’d be safe to do this and PE concurrently (though not on the same day, probably) as I don’t believe PE really has much effect on the inner urethra (just my opinion though).
Ttt, do you have to be erect while doing this? Also, do you think, for the purposes of PE, the best type of sound would have a ‘head’ that is larger than the rest of the sound so as to create a changing pressure as you move it up and down (assuming you’re doing that). Finally, would you please describe for us what it feels like to have a piece of metal go that goes into the urethral tract, but stops before reaching the prostate.
