...that "true chastity doesn't begin until you want the cage off" Ok So say you have arrived there and you want that freakin thing off! How do you cope?
Lean into the wind! Imagine walking outside in a hurricane, wind so intense that you can’t fight it so you just lean into it and let it hold you up. Feel the power, be thankful for your key holder staying strong for you in your time of weakness so that they keep you locked and denied.
It's even worse when you write erotica, and have your dick wanting to be hard on a micro cage, aroused by the very thing you write. I have to pause, go outside.. even playing videogames until my small caged dick decides it's enough to torture me.
It’s very hard sometimes. No pun intended. Early in our FLR I used to try and steal a release for myself, but she can tell when that happens and it’s not good for the health of my balls. These days I share my feelings with my DOMME. She used to feel sorry for me and give me a full release. Now she has me do more tasks or chores or she will have me give her a long oral session. On rare occasion a ruined. This is our life and I am committed to serving her.
Here is an idea. Beg her. Beg her to let you give HER an orgasm. Yes, you'll still be horny but you'd be amazed how good it can be.
I embrace the mantra "Embrace the Suck" (ironic and no pun intended). The US military adopted this term to refer to being mentally strong and resolved in bad times knowing that getting through the bad leads to better times. It truly has helped me as I've adjusted mentally to being 24/7 locked.
Meditation, physical work, wrapping myself around her. But really, just find something that will help to disspate that energy, and avoid porn or any other fruitless wastes of time. Do the plank exercise, and work up to longer and longer. A couple of weeks at it I went from around 60 seconds to over 10 minutes. If nothing else, it is a fortifying meditation with benefits.
