I haven't really practice to the point of not ejaculating at all but I have learned to control when I ejaculate. You can read the two posts that I shared where I practiced.
I just recently came across Mantak Chia's videos and tried to digest what he was sharing in terms of the theories and techniques.
I have to say that after practicing what he was saying, I think it added another dimension when punting.
You have to really vet out which partner you are selecting to practice with. Not all partners are willing and able to practice with you.
You can start by looking at the videos of talks by Mantak Chia, Solla Pizzuto, Charles Muir. You can start with practicing yourself and then when you understand some basic elements then you can find a suitable partner.
I would assume that you can attend one of the workshops to get more hands on guidance from one of the masters and find out if their techniques would be beneficial to you.
