A skilled edger will use this method to stay near the cresting point for a long time.
This is sometimes referred to as dick surfing. Of course, as he nears the cresting point, the best way to avoid going past the point of no-return is to avoid all contacts as you can see later (1:27). The edger’s goal is to find the appropriate level of stimulation to stay in the pre-orgasmic zone without going over nor losing it.
Even if he stays in control, the yearning to ejaculate will swell over time to a point where the edger’s mind will be consumed by this intent. His erection will be supreme. The pressure at his cock’s base will be unbearable. Orgasm will grow to be an obsession and everything else will become irrelevant.
At this moment, the edger morphs into a resolute masturbator (1:43) and nothing can stop him from spilling his seeds (1:46) ! Bliss.
