I'm a married guy in his thirties. My wife and I have had occasional fun with chastity ever since our marriage began about ten years ago. We both go through phases of interest with it. Initially we'd play for a few days. Now it seems we are going to break our old record for consistent use. Neither of us (as of yet) is really that interested in the orgasm denial potential of chastity play. I think our shared liking of it stems from how I enjoy it as a way of giving up control to her, and she enjoys that I enjoy her control of me. There has been some talk about trying to extend the time in lockup over this summer, but even extended durations in our case would be paltry compared to what I'm guessing several of the male users on here experience.
Play your play, it will be for you and her only, no need to mimic what others are doing. That said, a longer locking up will give much pleasure for both of you, for those who doesn't have done it already it is hard to believe but it is true. Have fun, this the most important.
Thanks for the welcome everyone, and thanks for the encouragement to do it our way. I would be interested to see what's behind door #2 some day. Maybe she and I both will. I wasn't offering an apologia for our way of playing with chastity; I was just letting those who might be interested know where I'm coming from with respect to it.
