My master and I are both happily married. Our spouses are okay with us being master/pet - as long as there is no sex involved. Verbal teasing and flirting is okay, but that's about as far as it's supposed to go. He's also in a position where he can acceptably control me around others in our social group, so there's plenty of opportunity for orders and taking care of my master. It's expected in our community.
Unfortunately, the only dom/sub situations I've been in were seriously sexual. I'm trying to please my master by obeying immediately, using titles and being observant. There's got to be more I can do, though. What are nonsexual ways you have pleased your dom?
EDIT: My master is new to a nonsexual concept as well. Any advice for him would also be wonderful.Edited:
