How frequently do you have Tease and Denial sessions?

My wife and I began experimenting with male chastity about a year and a half ago, and it’s going well. I’ve switched from a CB-6000S to a MatureMetal Jailbird, which has led to longer lockups—exactly the direction I hoped we’d head in. I’m all about her controlling my orgasms and deciding when I get pleasure, but I still want this to be about me too. For some reason, I imagine that other couples practicing this lifestyle have T&D sessions almost every night, while my wife isn’t quite as sexual; perhaps we shouldn’t be doing it (a bit dramatic, I know). This board has been incredibly helpful with many things, and the people here are great. So please let me know honestly: How often do you have T&D sessions? Do you go days where sex isn’t even discussed? Have your hopes ever gotten up only to end in disappointment because nothing happened? How did you handle the urge to top from the bottom instead of just giving up control?
