My penis is extremely girthy - over 7” mid shaft and 7.5” at the base. That’s well over the circumference of the average man’s wrist, for example.It’s difficult for a guy with my size to find rings that don’t snap, and that are comfortable to wear. This product is great because the multi size rings let me take on or take off the rings as things get more intense. If my partner is having a hard time taking my size, I can move up to the larger ring, till she loosens up a bit more.It’s also nice to have options to put a ring on my shaft, as well. That’s not usually an option because most rings are too tight and can get stuck in place very quickly, making things a little scary until you can get it back off. A flexible ring to wear at the base of my shaft allows me to roll condoms down and they’ll actually stay put, rather than rolling back up. Major plus for guys like me, it makes condom wear possible instead of a frustrating experience with breakage and rolling off when things get intense.These rings are made of a nice material that is flexible but also still durable, and won’t snap if you have a lot of meat to pack in. The material also bites nicely into my pubes, which is great- no pulled hair.
