How I measured for my Custom Chastity Saint - the one I've been wearing for over 70 days 24/7

Here's how I measured myself for my customised Custom Chastity Saint.

• I did my measurements when warm but not aroused.
• I used this cheap caliper off Amazon:

Over on the Custom Chastity website, Lady Fox asks for the Base Ring size, plus these measurements:

Base Ring Size: This is a dark art! Snug, but such that your erection doesn't crush the tubes of your testicles. (I got there by trial and error, but you might try getting a really good hard on, then using a measuring tape. If you are really desperate to get it right, buy a tub of Polymorph Plastic (soft at 60 degrees C) and make your own prototype base ring.)

 

A: I don't have a very long dick, so don't need much bend in my devices. I therefore measured my dick by laying it on the edge of a table and pressing a toothpast box against the tip. Then measured from the edge of the box to the root of my dick.

B. Much harder! It can't be too tight otherwise arousal causes oedema and the penis gets stuck during turtling (we tried a super snug device - it was mindblowing but impractical). My solution was to measure my penis at the crown or corona:

In other words, I measured my penis girth at its greatest dimension - remember I did this will warm, but not aroused.

C: The dreaded "gap" is really hard to guess. It's better to be a little loose than too tight. You'll have to work that out for yourself. Bear in mind that the smaller the B measurement - the tube - the geometrically larger the actual measurable gap between tube and ring.

For my custom device, I needed a fourth measurement:

D: The length of the tube up to what you could call the lip:

This turned out to be really critical for preventing turtling. I've marked the sweet spot using a blue dot:

The lip should press securely on the corpus cavernosum, meaning the meat of the penis. It should not press into the valley just behind the head.

I'm circumcised. The ideal location on me is before the start of my circumcision scar. If you are uncut, then you're probably looking for the point before where your foreskin begins.

This makes the head section of the device seem a little swept back compared to standard (the pink one is the new version):

However, I find it prevents most turtling - the penis seems to curl up before it retracts, and that's the sweet spot for preventing it escaping - and my erections never get stuck in the cage.

The end result appears to be wearable indefinitely:

This is what worked for me. You mileage - as they say - may vary...
