Excellent. It sounds like you're fully adapted to your status as your sexy wife's cock-locked in-chastity cuckold, with her your sole key-holder — all of which seems totally appropriate as she pursues her affairs with her lovers.
I was slightly concerned as to whether you were holding up OK, what with not being able to give yourself hand jobs while thinking about what your sexy wife might be doing with her lovers. But, it sounds like you are. Congratulations for adapting well to your cock-locked and cuckolded status in your marriage.
