1.  An extremely complext technique often taught from childhood to young Tantric boys. As a result of this practice, the Tantric male can literally draw into him female sexual fluids as a result of her orgasm through the urethral opening of his erect penis, much like using a straw to drink fluid. Some Tantrics say that the male is only drawing in the female energy. According to the book called the Shiva Samhita, there are two aspects of this. If the male doesn't ejaculate during this process (usually considered the preferred method), it is called Sahajoli. If he does ejaculate he is expected to draw in the combined fluids or energy. This is called Amaroli.

2.  The contraction of the muscles around the urethra near the base of the penis. See Sahajoli Mudra.
