Humbler has got its name from the word humble, because who wears it, becomes humble in a minute. It comes from behind on the top part of scrotum, between the penis and the testicles. It hangs then between legs and ass, it leans on the legs from behind and it pushes the testicles behind the body.
Humbler is useful in the BDSM world to control submissive men. It makes difficult for them to stand up straight. When bent or on all fours, humbler makes nearly no difficulties, but when the man would try to stand up, he will feel unpleasant and painful scrotum thrust and squeeze of the testicles.
Humbler is a unique tool for dominant women. Put the humbler on to your man or slave and show him, where is his place and how he should behave in your presence. He will kneel at your feet and look up at you from below, in case you let him. It will be very humiliating and educational for him. Together with cuffs or ropes, humbler can be used in bondage as well, to restrain the man in various uncomfortable positions. Moreover, his testicles are unprotected and very vulnerable at that moment, which can be effectively used in his training as well. Same as his ass, with attached humbler ready whenever for the educational spanking or any other BDSM games.
Don't leave the humbler wearer without control. Watch blood perfusion into his scrotum. Don't force him to do any intense moves. Don't put him into extremely painful positions or positions, in which he could lose balance. Don't forbid him to use the safe (stop) word.
