Seeking guidance regarding sensitivity after long-term locking up

My wife and keyholder put me in chastity nearly a year back. It’s been essentially constant, with only rare breaks where I wasn’t locked up. While I adore her ownership of my penis and orgasms, and love that moment when I really need to touch her, I sense she isn’t entirely sold on it all the time—though more often than not, she clearly enjoys it.

The issue right now is that during our sexual encounters after an unlock period, my sensitivity is heightened because of how long I’ve been locked up. Consequently, I reach climax much faster than usual. I try hard to last longer, but I worry I’m neglecting her satisfaction since she’s already at the edge.

Any suggestions? Cheers!
