>>20233555Pelvic floor muscles have to be trained to be able to close the urethra hard enough to impede ejaculation while forcing the cumming to still happen until fully done.
You can start by simply pushing hard your perineum against the chair when you are going to cum and tight your urethra muscles to stop the shooting.
Progressively train yourself into continue fapping until the whole cumming is done.
Advance into not needing to push against a chair and being able to close your gate on demand in any position.
This won't lower your sex drive and much as free jeezing and allows to immediately continue with a new round. Also the juices are absorbed into your body so there is no energetic or chemical waste.
Enjoy a new level of clean strong cumming.
