If you and your partner are interested in exploring chastity, chances are you’ve already started looking at different cages and wondering, How do I even pick the right size? Don’t worry — you’re in the right place. Measuring your man for a chastity cage might feel a little intimidating at first, but with a little guidance (and maybe a little fun along the way), you’ll feel confident in no time.
This guide is here to walk you through the basics, step-by-step, in a calm and judgment-free way — so you can focus on enjoying the journey together.
First: Keep It Fun, Keep It Light
Every body is unique, and finding the perfect cage can take a bit of trial and error — and that’s completely normal. Chastity isn’t a one-size-fits-all experience, and it’s okay if the first cage you try isn’t the one. Many couples try a few different sizes or styles before landing on what feels right.
If you’re just starting out, it’s smart to experiment with more affordable cages first — especially if you’re not planning on long-term wear just yet. You can always upgrade to a high-quality, permanent cage later once you know what fits and feels best.
Understanding the Basics: What Are You Measuring?
Chastity cages usually have two main parts:
- The Ring: This goes around the penis and testicles.
- The Cage: This part encloses the penis and keeps things locked up.
Getting the right size for both the ring and cage is important for comfort, safety, and effectiveness — and no, you don’t need to be an expert to get started.
Measuring the Ring (Gently!)
The ring is worn behind the genitals and helps keep everything in place. You want it to be snug — not too loose, and definitely not too tight.
Two Easy Methods:
1. The String Method
- Wrap a piece of soft string around the base of your partner’s genitals.
- Mark where the ends meet.
- Lay the string flat and measure the length with a ruler.
2. The Tape Measure Method
- Use a flexible measuring tape to wrap around the same area.
- Note the measurement in millimeters.
Once you have that number, add around 10–12% to find a good starting ring size. So if you measure 40mm, consider starting with a 45mm ring.
💡 Tip: A well-fitting ring should allow you to comfortably slide one finger underneath when it’s being worn.
Measuring the Cage Length (It’s Easier Than You Think)
The cage should be short enough to hold your partner’s penis securely when it’s soft, but not so tight that it causes pain. A snug fit helps prevent any unwanted “slipping” or stimulation.
- Start by measuring your partner’s penis while fully flaccid — from the base to the tip, along the top side.
- Then subtract about 10% from that measurement. This ensures a comfortable but escape-proof fit.
Shorter cages are usually always better, as they reduce chafing and make everyday wear easier.
TL;DR
Ring: Should be snug but not tight — you should be able to fit one finger underneath comfortably.
Cage: Should match the length of your partner’s soft penis, minus about 10%, for a secure and comfy fit.
Final Thoughts
Remember: chastity is a journey, and part of the fun is learning together. Don’t be afraid to experiment, adjust, and talk openly about what feels good — or doesn’t. The right cage is out there, and when you find it, it can unlock a whole new level of trust, intimacy, and erotic play between you and your partner.
