Poses︎︎︎

1. Vajrolī Mudrā - The mudra requires the yogin to preserve his semen, either by learning not to release it, or if released by drawing it up through his urethra from the vagina of "a woman devoted to the practice of yoga". The yogin is instructed to practice by using his wind to hold back the urine while he is urinating, and then to release it little by little. After six months' practice he will in this way become able to hold back his bindu, "even if he enjoys a hundred women".

you get into that position, then do bellows breathing (In and out with the abdomen like a pump) then on the final deep inhale contract the anus and hold (Mula bandha). Then release, contract, release contract (That’s ashvini mudra)
