We've been into male chastity play for at least 10 or 11 years now. We've taken short breaks here and there on vacations and such, but I live in a cage pretty much 24/7 these days, except when she unlocks me for cleaning, teasing or once in a while (gasp!) sex. I'm unlocked substantially less frequently since we started down the cuckoldry path, and haven't spent a full day uncaged since last October. There are people who are more serious about complete denial than we are (many of them single and turned on by the fantasy, I think), but my release has been at my wife's sole discretion for years, and that suits us both fine.
