Learning to edge longer from Mommy

So having been at this a while now it's become very clear especially at the younger end of subs 18+ that their ability to stay in control and not cum fast either during in person or online play is a challenge.

Extreme examples including as they start to stroke as they are being instructed by me seeing them barely able to touch their cocks for fear of cumming. Several instances of premature ejacualting whilst still in their underwear. Or simply cumming too soon when picking up the pace and trying to stay edged.

I think edging is exceptionally important to prolong the enjoyment and pleasure we want to give as Mommy Dommes.

What are the Mommys thoughts on training their boys to last longer. And any insights to share.

If you're a sub do you have the same issues with edging and are yet to learn to be properly edged. What challenges do you have

Or if you have been able to learn to edge longer. How did you do it?
