It should absolutely be mandatory. I've been caged for a couple of months and couldn't be happier. My gf and her Black bulls have more sex and I'm more eager to serve them.
Also, even if castrated or sterilized chastity should be mandatory. Maybe one can remove one's balls but the cage should stay on.
