Female led relationships discussion

Over the past few years, I’ve been presenting my wife with what I term a ‘behavior gift’ for her birthday, which is coming up in about two weeks. The goal is to establish a lasting behavioral shift that inconveniences me while providing her sexual arousal—or at least showcasing my submission. Initially, this meant wearing a chastity cage nearly all the time. Then came the switch to only thongs. Next was fasting during Ramadan annually in her honor. Finally, I effectively banished the word ‘no’ when speaking to her. Now I’m running low on inspiration. Although I’d enjoy becoming her sissy and donning women’s attire that stands out outside our home, she isn’t keen on it.

Does anyone have suggestions? My current top contenders are serving as her ‘whipping boy’ or committing to wearing a tie every single day, though the latter feels somewhat mundane since I already do so frequently.
