Letting Go of the Lock

Hi everyone, this is my very first post here. I believe I am completely ready to give up on chastity. My wife acts as my key holder and says she enjoys the role. However, whether I’m locked or even when I’m not for that matter, I receive little to no attention. When I stay locked for long stretches, my frustration builds and builds and it feels like it has nowhere to go. It’s almost like people just say, “Oh sure, you enjoy being lock, keep it on.” Or if I don’t want to be anymore, they ask why did I agree? It seems as though my sexual needs mean so little to my spouse that I’m simply neglected. As for her own desires, it feels like she has none of them. When she gets horny, she sleeps with other men and only stays intimate with me because “she loves” me deeply. I am so lost right now that I don’t even know who else to talk to. My therapist doesn’t quite get it, my friends are too conservative, and my wife is brushing me aside. So here I am posting on an Internet forum.
