I never thought this was possible!

This is the best fitting and most comfortable cock ring I have ever tried. I resigned myself to the idea that I was not a “cock ring guy” as I have never found a cock ring that fit me until now. Despite trying MANY different rings types and sizes. The curve along with the key hole contour to my body and leaves room for my balls to hang a little more freely and that makes ALL THE DIFFERENCE! I’m recommending Primal to all of my friends and looking forward to trying some of the other types of rings in the future!

Comfortable

I use a 55mm in the titanium and decided to buy the 50mm in the silicone to just in case because of the stretch. Not as stretchy as I thought it was going to be and probably should have sized up. But that was just me testing it out. Highly recommend but the titanium is my favorite if you know your correct size

I owned both silicone and 2 metal ones

I love these so much i have 4! The metal ones are nice but these silicone are so comfy with this one being the most comfortable of them all! I bought the 45mm in the other silicone and was comfy but the 40mm in this one gives me that nice hardness i was looking for. The metal ones i wear in 55 and 50

It’s loose not like the metal one , I don’t recommend

Thanks for your review! The interior dimensions of our silicone rings are the same as our metal rings, but silicone will flex a bit. We want to make sure every guy gets the perfect fit, so please reach out to our team for help!

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.
