Chastity and orgasm denial discussion

Recently due to being caught masturbating to pornography I voluntarily locked myself into one of my pink Holy Trainer V3 size small chastity devices before leaving my Queen on business. I left a letter in an Andrew’s Jewlers necklace box along with the only two keys for my device which were of course tethered to a gold necklace. My wife appreciated the gesture but quickly informed me that she will release me as soon as I return home which will be tomorrow. I know she does this because she is being merciful due to the pain I experience at night when my wee wee gets erect while sleeping. I have read countless posts on how to prevent the burning sensation experienced from trapped ball devices and know I need to apply adequate lubrication on the ring when I experience this pain. Many have said that over time your balls will stretch and this pain will subside but I have never been in chastity long enough for this to occur. Part of me believes the pain is appropriate because I can not be trusted and I hurt my Queen by masturbating to nasty unrealistic porn. Despite this my Mistress is content on always removing my device. I believe I belong in chastity for much longer periods of time. I feel this will not only keep me from humping my diapers without permission but it will also keep me much more devoted and submissive to my Mistress. So what do I do? Mistresses are always right and if she does not want me in chastity very long then I am to respect that yes? I would really like my Queen to feel the power chastity can give her but I do not want to beg her to lock me up on a more regular basis.
