URINE

After the tantric practice, you can check your urine for signs of seminal fluids. You may find dispersed clouds, white strings, rubber-like semen, or foam on the surface. Pre-cum does not appear in the urine visually, so any trace signals a partial failure of the technique even if no drops were seen before and the penis remained erect. A retrograde ejaculation can be triggered through PC muscle flexing since it can redirect semen into the bladder. Alternatively, some semen can simply be stuck in the urethral bulb.
