Is it acceptable to request release of my load?

Alright! I started wearing the lock back in January. It’s unusual for her to keep me locked up longer than a day or two, and this time it is truly INTENSE. My main desire right now is to release myself; I absolutely need to cum. Each night when I wake up, my body tries to get hard, which makes things… quite uncomfortable.

But what’s the best way to bring it up? I want to make sure she understands that ultimately, it is her call. She isn’t obligated to say yes just because I’m asking, nor must she refuse simply because she suspects I might secretly be hoping for permission. It is entirely her choice. What she decides stands firm. While I do hope to reach a point where we go once annually in the future, that time hasn’t come yet.
