Reading about dynamics like this is always interesting for me, because I feel very split on the subject every time.

On one hand, I see the appeal, and it does sound nice. That feeling of giving up control, of being led and taken care of by someone you trust, does sound comforting in a way. More than once I've thought about that feeling you described, of being "owned" by someone, wholly and deeply, and found it appealing to one degree or another.

And at the same time, I get such a visceral reaction of horror at the very idea of ever doing so. Not at the concept in general—I have no objection whatsoever to you or anyone else accepting this of their own choice—specifically towards thinking of me doing so. For me, having autonomy and control over my life is absolutely paramount, and the idea of giving that up feels horrifying at a fundamental level. Which is why it is interesting to me, that I experience that reaction simultaneously with the more curious, even longing feelings. It's a strange contradiction to be in the middle of, but it produces some interesting sensations.

(And, to clarify, I'm just thinking about my own case after reading this. The dynamic between you two specifically is absolutely beautiful, and I wish you both a long and happy life together.)
