Chastity calculator

Chastity calculator: your lock-up time and unlock date

The chastity calculator on this page draws a random number of days from the range you pick, from a first try of 1 to 3 days to two weeks of 10 to 16, and shows the date you unlock. Let the first draw stand, let a keyholder overrule it, start short, and keep hygiene unlocks and an emergency key throughout.

At a glance

  • The calculator below has four ranges: a first try of 1 to 3 days, a long weekend of 2 to 4, a week of 5 to 9 and two weeks of 10 to 16.
  • Each draw is a whole number of days, every number in the range equally likely, with the unlock date counted forward from today.
  • Nothing is kept or sent: the result lives only on your screen, so write down the number and the date before you close the page.
  • If you have a keyholder, She sets the time and may overrule any draw; use the calculator only when She tells you to, or on your own for a first try.
  • No number outranks your body: keep hygiene unlocks and an emergency key, and remove the device at once for pain, numbness, swelling or a change of colour.
  • This page is general information, not medical advice; if you have a condition affecting circulation or skin, speak to a doctor before you lock.

Chastity calculator

Draw your lock-up time

Choose a range and draw a length. If you have a keyholder, She sets the time, not this page: use it only if She tells you to, or on your own for a first try.

Keep an emergency key where you can reach it. Unlock for hygiene, and at once for pain, numbness, swelling or a change of colour.

How the chastity calculator works

The calculator sits just under the key facts. Pick one of the four ranges and press the button: a number of days appears, with the unlock date written out as a weekday and a date. Once a time is showing the button stops working, and only choosing a range again clears the result, so a second draw is always a deliberate act.

The date is counted from today: draw five days, lock this evening, and unlock at the same hour on the date shown. Unlike the random-duration tools in the chastity apps guide, this one tells you the answer at once, so the suspense lies in the waiting. It holds no key and no code, and the lock is still yours to open.

Which range to choose

The ranges climb in steps, and each assumes you managed the one before it without a warning sign. Choose by what your body has already shown it can do, not by what you hope it can do.

  • A first try, 1 to 3 days: for someone new to lock-ups. First wear the device at home for short spells while awake, then for a full day, then for a night, as the chastity cage safety guide describes, and draw only once each of those passed without complaint.
  • A long weekend, 2 to 4 days: once a first try ended cleanly. Plan a hygiene unlock in the middle and look at your skin each time.
  • A week, 5 to 9 days: after a weekend that left no marks and cost you no sleep. Mark the hygiene unlocks on a calendar and write a report at the end.
  • Two weeks, 10 to 16 days: only after a full week went by without a warning sign. Agree a review near the halfway point, and be ready to stop early.

Why the first draw should stand

The calculator exists so that chance, not you, chooses the number. Drawing again until a figure suits you puts you back in charge and turns the lock into a wish, so write one line in your log saying the first number stands, and then press the button once.

Two things may still change a draw. One is safety: no draw outlasts a warning sign, and unlocking for your body's sake is never cheating. The other is life: travel or illness can pause or shorten a lock, recorded honestly. A number that merely feels long is no reason to redraw, but one longer than any lock you have managed before means the range was too ambitious: step down a range, note it in your log and draw once from there.

When a keyholder overrules the draw

If someone holds your key, the decision is Hers and the calculator is only a suggestion. Use it when She tells you to, or offer Her the result to keep, change or set aside. A keyholder may add days for a broken rule or take some away for good reports, within the ceiling your written terms allow, as the chastity rules guide shows. At home, a wife or partner can simply press the button herself; the chastity in marriage guide covers that arrangement.

With one of DominatrixCam's own Mistresses, send Her the number and the date in a message, which carries text only, and accept Her decision when She gives it. If She names a term in a private, you listen with your camera and microphone off and no chat box open, and She never sees, hears, reads or answers you while it runs. Private time is billed per minute at Her own rate in US dollars. A visual check needs cam2cam, sold only in LiveJasmin partner rooms marked ↗, as an extra paid in that site's credits.

Building up from one range to the next

Move up one range at a time, and only after the last lock ended with clean skin, decent sleep and no warning sign. Rest for a few days between locks so that each starts from skin that has recovered, and let any problem send you back a range; stepping back is part of building up, not a mark against you.

Keep a short log for every lock: the date it closed, each hygiene unlock, how your skin looked, how you slept and the date it opened. After a few locks it tells you more than any range can, and it is exactly what a keyholder wants to read. If a whole month is your eventual aim, the Locktober guide shows how the same steps lead up to October.

Staying safe while the lock runs

The date on the screen is a target, never a duty. Whichever range you drew, these rules hold on every day of the lock:

  • Unlock for hygiene on the schedule you wrote down, wash and dry the device and yourself, and look at your skin before it goes back on.
  • Keep an emergency key you can reach in seconds, for example in a sealed and numbered envelope, and never lock your only key away.
  • Take the device off at once for pain, numbness, swelling or a change of colour, and leave it off until your skin has settled.
  • If night-time erections keep you awake, take the device off for the night rather than enduring it.
  • If a device will not come off, or swelling does not settle after removal, see a doctor instead of waiting for the unlock date.

When the time is up

On the unlock date, open the lock at the hour you agreed, wash, and look at your skin before anything else. Leave the device off for a few days, however well it went, and write a short review: the number you drew, how the days felt, where it was hardest and whether you would stay in this range or move up.

Settle what the unlock means before the lock closes, not on the day. A release may be allowed, ruined or put off for longer, as the tease and denial page explains, and with a keyholder that choice is Hers. To find one, open the chastity view of the browse page, or read the online keyholder page to see how remote keyholding works.

Questions people ask

How does a chastity calculator work?

You choose a range, and it draws a whole number of days within it and shows the date you unlock, counted from today. The one on this page has four ranges, from a first try of 1 to 3 days to two weeks of 10 to 16. It holds no key and keeps no record.

Should I redraw if my lock-up time feels too long?

Not because it feels long: keeping the first draw is the whole idea. If the number is longer than any lock you have managed before, the range was too ambitious, so step down a range and draw once from there. Safety and real life, such as illness or travel, can always shorten a lock.

How long should a first lock-up be?

Short, and only after you have built up to it: short spells at home, then a full day, then a night, checking your skin each time. Once all of that has gone without complaint, the first-try range of 1 to 3 days makes a sensible first lock, with hygiene unlocks and an emergency key.

Does the chastity calculator remember my unlock date?

No. It stores and sends nothing, and the result disappears when you close the page or choose another range. Write the number, the date and the hour you locked in your log, and send them to your keyholder as a message if you have one.

What if my keyholder wants a different lock-up time?

Then Hers is the time. The calculator offers a suggestion for a keyholder to keep, change or ignore, within the ceiling your written terms allow. What She cannot override is your emergency release: pain, numbness, swelling or a change of colour means the device comes off at once.

What should I do when my chastity time is up?

Unlock at the agreed hour, wash and check your skin, then leave the device off for a few days before the next lock. Write a short review of how it went and follow whatever ending you agreed beforehand. With a keyholder the ending is Hers, and your review goes to Her as a message.

Can I unlock before the date the calculator showed?

Yes, for safety, at any time and without asking first. Pain, numbness, swelling or a change of colour means the device comes off at once, and a planned hygiene unlock was never a break in the rules. Tell your keyholder afterwards in writing, and if a device will not come off, see a doctor.
