Chastity training: rules, tasks and the chastity contract

Chastity training means building up time locked in a chastity device under rules set by a keyholder. Wikipedia's BDSM glossary defines chastity as being prevented, often with a locking device, from access to or stimulation of the genitals except at a partner's choice, and training as the dominant's ongoing effort to teach the submissive how to behave the way she prefers. Put together, that's exactly what chastity training is: a lock, and a set of rules that shape everything around it. This page covers pacing, rules, tasks, games, the chastity contract and what's actually known about long-term chastity.

What chastity training means

There's no official definition of chastity training, but in practice it has two parts. The first is wear time: getting used to a device gradually, from hours to days to longer stretches. The second is behaviour: daily check-ins, tasks, rules about dress or manners, and a keyholder who decides when the device comes off. Wikipedia notes that devices are worn either for a limited period or as a long-term arrangement, and training is how people move safely from one to the other.

The appeal is rarely the cage itself. It's the constant, low-level reminder that someone else is in charge, which colours a whole day. Our guide to male chastity covers devices and fit; this page is about what you do once you're locked.

Building up wear time

Go slowly. One domme quoted by the Daily Beast tells new subs to check in daily and to train their bodies to get used to it by increasing their locked time slowly. Eli Shaw, speaking to PinkNews about Locktober, put the limit more bluntly: a whole month of chastity is too long for most people without experience of being locked.

A sensible ladder looks like this: a few hours at home, then an evening out, then overnight, then a weekend, then a working week. Move up only when the last step was comfortable. The International Society for Sexual Medicine advises wearers to periodically check how the penis and testicles feel, and any pain, swelling, numbness or skin change means the device comes off, whatever the schedule says. Our chastity cage safety guide lists the warning signs in full.

The rules keyholders set

Rules turn a device into a dynamic. The most common are:

• Check-ins. A message at set times, often with a photo as proof. Apps print a unique code on proof photos so they can't be reused.
• Hygiene openings. Scheduled, short and non-negotiable for health, sometimes supervised by video call or tracked with numbered plastic seals.
• Denial rules. What's allowed while locked and what isn't, including whether teasing sessions are part of the arrangement.
• Dress and conduct. Something worn as a reminder, a form of address, manners at home.
• Reporting. A short daily journal of how the lock felt and how the tasks went.

Keep rules few and clear at first. Every rule is something the keyholder has to remember and enforce too, and a short list followed well beats a long one followed badly.

Chastity tasks

Tasks give the locked partner something to do with all that attention. One keyholder told the Daily Beast he sets a daily routine that helps his subs learn a new skill, and avoids orders that might be dangerous or impossible to follow. That's a good test for any task. Popular choices include:

• A daily journal entry about the lock, the day and the keyholder.
• Exercise, a walk or a stretching routine at a set time.
• Household service: a chore done to her standard, not his.
• Learning something: a language, an instrument, a recipe for her.
• Writing lines or a short letter of thanks.
• A tease session, in person or on cam, ending exactly as she decides.

Apps have made task lists into a genre of their own. Chaster lets a lock carry up to 100 different tasks, assigned at random, chosen by the wearer or voted on by other users, with photo proof stamped with a six-digit code.

Games and penalties

Games add uncertainty, which is half the fun of being locked. Dice decide how many days are added or taken away. A hidden timer means nobody knows the release date. Chaster's Guess the Timer adds three to six hours by default for each wrong guess. Penalties for missed check-ins can include adding time or freezing the timer, and the app's own documentation warns that a freeze with no way out can leave someone frozen indefinitely.

That warning is the point. Penalties should be proportionate, time-limited and agreed in advance, never open-ended. Adding a day for a missed check-in is play. A rule that can trap someone in a device with no end date is a safety problem.

The chastity contract

A chastity contract is a written version of the arrangement. Couples have been writing contracts like this for decades; a 2014 Harvard Law Review note found they typically cover the duration of the relationship and the hygienic or sartorial requirements of the parties. A good one covers:

• The length of the lock, or how the release date is decided.
• Check-in times and what counts as proof.
• Hygiene openings and how they're handled.
• Tasks, rules and penalties, with limits on each.
• Emergency release: when it happens and how, with no argument.
• A review date, when either person can change or end it.

It isn't legally binding, and it shouldn't be. The same Harvard note observed that practitioners seemingly don't intend or ask for legal enforcement; the contract is a tool for thinking things through. Chaster's design makes the key principle explicit: unlocking, resigning and triggering a safety mechanism are not permissions, and they can never be granted or taken away. Our BDSM contract guide covers writing one in more detail.

Long-term chastity

Some people stay locked for months or years. Slate profiled one man counting past day 2,165. Medicine has very little to say about this, and that's the honest headline. A May 2026 expert opinion in the Journal of Sexual Medicine described wear ranging from months to years, found no clinical studies, and could offer only hypothetical frameworks for possible harm. The International Society for Sexual Medicine, writing in August 2026, reported limited evidence of a fertility risk from heat and stressed clear consent and talking to health care providers where needed.

Fertility deserves a note of its own. A 2026 review found abstinence of four to seven days or more was linked to reduced sperm motility and more DNA damage, and advised ejaculation every one to two days for couples trying to conceive. Long-term chastity and trying for a baby don't mix.

Myths worth dropping

Two claims circulate constantly. The first is that testosterone climbs the longer you're locked: the famous figure of a 145.7% peak on day seven comes from a 2003 study that was retracted in 2021. The second is that the ache of denial is dangerous. A 2023 survey of 2,621 people found severe pain from arousal without release occurs only in a minority, and the authors noted it's never a valid reason to continue unwanted sexual activity. Chastity is a dynamic, not a health regime. Our page on orgasm control covers the evidence on denial.

Training with a keyholder on cam

Not everyone has a partner who wants the key. Some people use a timed lockbox or an app and report to a cam mistress, who takes check-ins, sets tasks and runs tease sessions on camera without ever seeing anything you don't choose to show. October is the busiest month for it, thanks to Locktober. The strip at the top of this page shows women live now who list chastity, denial or JOI; our chastity cams page explains how those sessions run, and the keyholder guide covers choosing the right person to trust with the key.
