The PG Pump is actually an ancient Taoist technique to delay ejaculation and can also be used during orgasm to prevent ejaculation. To use the PG Pump you must first find your external prostate point. The point is located on the perineum between your scrotum and anus, but closer to your anus (Figure 1). The PG Pump technique can be applied with or without pulling out, however the effect is greater if you do pullout.
