My New Favorite Ring!

I'm obsessed with Primal rings... I already owned a metal Primal ring prior to purchasing this one and use it everyday so when I saw that they came out with a silicone one I immediately had to get both of the new models. The Power Flex ring is by far my most favorite. The contour shape and fit makes it so comfortable for extended wear (when flaccid) to the point that I sometimes forget that I have it on throughout the day. Not to mention, the wider and flared edges on the Power Flex really pull my package up and out at the base giving it more support and making my bulge more prominent looking. When erect, it fits nice and snug keeping the blood flowing to my penis making it rock hard and my veins throbbing. Also, it's tight and comfy enough to keep a semi when I'm edging during my solo/bate sessions. The silicone material definitely makes it easier for quick removal. This ring is overall a winner and I highly recommend it.

Lastly, S/O to the team at Primal Rings for your stellar customer service. My order was received quick and the personalized note in my package was a nice touch. I'm a customer forever. Thanks!

Comfortable

The ring fits and feels great, better than anything else I've tried. I forget it's on, and it also keeps everything well placed.

Excellent

Went with silicone for my first one. Have to say very pleased . Very comfortable. I wasn't sure on the sizing but turns out, I was correct and it's a perfect fit. I'll roll with this one for a bit, then I'll probably try an aluminum one...

Nice and snug

I ordered 2 satin black silicone power flex rings, each a different size. That is to say sizes 40 and 45. Could not resist the sale that was going on at the time. While I love both rings, I really have to lube up in order to get the 40 on. I only wear this 40, maybe 2 hours at a time. Really quite snug. On the other hand, the 45!! It is nice, fits well, holds me and the boys comfortably all day. All that to say; size does matter!!!

How to measure for the perfect fit

Gather Your Supplies. You'll need a piece of string and a ruler to get your measurement. We recommend using a string instead of trying to use a soft tape measure.

Measure. Wrap the string around your penis and behind your balls. Mark the string where it meets. You want the string quite snug. You should be able to just fit a finger between your skin and the string when you're soft. And it should be comfortably tight when you're hard so that you can't fit in a finger. You may want to measure both soft and hard to double-check your size.

Determine Your Size. Measure the distance from the end of the string to the mark.  This is the circumference.  Use the handy table below to get your size.

Circumference Ring Diameter
13.0-14.5cm (5.0-5.75in) 40mm (~1.6in)
14.5-16.5cm (5.75-6.25in) 45mm (~1.8in)
16.5-18.0cm (6.25-7.0in) 50mm (~2.0in)
18.0-19.5cm (7.0-7.75in) 55mm (~2.2in)

Tips For Measuring

  • Most guys are in the 40mm-50mm range.
  • 55mm is a pretty big ring. So if you're not bigger than average, try measuring again and make sure you pull the string tight.
  • If you have a good-fitting round ring, MEASURE ANYWAY. You may find your Primal ring size is 5mm (~.2 in) smaller than your round ring size. Our keyhole shape fits a bit looser than a round ring with the same diameter.
  • Measure twice!  Due to the intimate nature of these rings, we can't accept returns or exchanges.
Remember: Safety first! Do not wear a ring that is too tight, and remove the ring immediately if you feel discomfort, a sensation of coolness, observe any changes in color, bleeding, or feel tingling or numbness. If in doubt, take it off. Men with pre-existing genital conditions or injuries, or those taking anticoagulants should consult their physician prior to use. Cock rings should not be worn for more than 30 minutes, and you should not sleep in a ring.
