I’ve trained myself to edge for an hour or more and then bring myself to the “edge” and then stop – then flex my cock muscles and shoot out some cum, then pause and go to the “edge” again, flex again and shoot out more.
Usually 2-3 times. Harder to control each time. For the final stroking (can’t hold back) I often I fill my hand with cum and use it as wonderful warm lube . Then I go for broke and shoot a major load. My orgasms have gone from being experienced mostly in my genitals , to being an experience where my entire body experiences “pins and needles” which is very pleasurable– while I’m sort of having an out of body sensation. And at the same time I have involuntary muscular spasms (small or large depends on how horny) along with major cum and a very intense orgasm.
