Female led relationships discussion

Hello, We are still relatively new to the chastity and FLR lifestyle, but we find it very engaging - I must confess that I really enjoy it. The main issue right now is finding a suitable name for him. Initially, he didn’t have a specific title. He started calling me ‘goddess,’ which sounded good in theory but felt strange when spoken aloud by him. We then tried ‘mistress’; however, as English isn’t my first language, I always associated that word with the other definition—the woman who has an affair with a married man. Since he belongs entirely to me, I told him I am not “that” kind of mistress. We have now discovered that ‘My Lady’ fits perfectly for both writing and speaking. But what about his name? I’ve noticed several options used here on the forum, yet none have made me feel completely confident using them so far. Could you share what titles are given to or used by your partners? It would be great if you could include a brief story explaining how you chose your title.
