Whats bigger than a Magnum XL? The only thing I heard was a “They Fit”, which does custom sizing, largest size is something around 10”, with similar girth to the XL Magnum
The Magnum XL is the widest available today that I’m aware of, yes. I was just emphasizing that at 6” girth, you do not need to ever worry that any condom will be too big on you.
As Andro said, an XL would probably fit just fine on a 5.5” girth.
Regular (or even “snug” sized) condoms can be stretched to fit the hugest girth (hell, they can hold gallons of water), but they will exert extreme force on your dick and will kill anything less than a rock-solid erection.
I wish someone would make a condom with a truly loose glans area (e.g., 7” circumference unstretched), so that a girthy glans wasn’t automatically pinched small by the condom (since this part of the penis can’t get as hard as the shaft).
