there are two "basic" styles of male chastity devices: ball traps, and full belts. Most of what you will find on Amazon are ball traps. Both styles have their pros and cons, and expect to go through several before finding a device that you finally decide on.

Full belts are the old school "steel underwear", though they are made with various modern materials. They are generally the most secure and comfortable for long term wear, but are expensive and almost always require custom fitting.

Ball traps, in whatever form and whatever vendor, are usually less expensive, but can be problematic to wear for more than a few days, as there is no reliable way for them to keep the penis from trying to inflate during the night, despite the advertising. Still, as an introduction, these are generally accepted as the best way to figure out if chastity is worth further investments.

While Amazon and its access to the "knock off" market is great for a lot of things, chastity devices are NOT on the list. Use it to get pictures of the different styles, but go directly to the manufacturer and pay the extra for a real device. The knock-off devices are often sized for much "smaller" people, made of crappy materials, not constructed with the precision that is critical for anything going on "that part" of the body, etc.

Before ordering anything, take the time to follow the sizing and measuring instructions provided by the vendor. You will be so much happier with your purchase if you do, and will end up spending less by not having to go back to order a size up or down of any of the components.

Lock the Cock dot com and House of Denial dot com have a fairly good representation of the more credible vendors and manufacturers, as well as the various substyles of ball traps. Lovegasm dot com has a good selection of "modern" belt styles. The only "classic" belt style provider I have been able to find lately is Fancy Steel.

Expect to spend more than you probably want to before finding the device you are ultimately happy with.

As far as a "keyholder" goes, don't worry about that until you find a device you can wear for more than a day or two. Once you have that, you can do little things like freezing the key, sending it to yourself in the mail, using Time Lock or Emalock and a "lock box" with a combination, etc. to extend your forced denial until you can find someone else to control your freedom.
