To "sex the black" the cigar must be unopened in its wrapper. Take it between your hands vertically (mouthpiece on bottom) and place hands flat against eachother and move hands forward/backwards alternately. Continue for a few seconds. Remove from wrapper.
This evenly loosens up the fine tobacco for a great smoke. Enjoy.
