I would just like to add my support to his_Pita's. Collaring and D/s vows are not something that are a part of my own BDSM life (such as it is), but if they were, and if my partner and I were to settle into permanent roles, I can't imagine that all the responsibility would fall on the Dom(me) to learn about new things.
I think it's wonderful, submissivewife, that your Master trusts you to take on this particular task. A smart Master realizes that his sub might have talents or interests that he doesn't share, and makes the most of their complementary abilities.
And if it were "fucking stupid," most of us would at least have the courtesy to keep that thought to ourselves.
