Control of male genitalia is the root of female rulership of the male.
Recalcitrant, errant males requite more than chastity devices and orgasm denial.
The penis and testicles are punishable parts of male anatomy. Penises can be pinches, whipped, scratched. Kicking, slapping, stretching a man’s scrotal sac reducing to a whimpering and whining slave who will do anything for release from punishment.
Genitalia are durable. And for men is the only workable method for instilling obedience and acceptance of inferior status.
Never fear kicking a rebellious slave in the balls.
