Condoms are usually made of latex or polyurethane. If possible you should use a latex condom, as they are slightly more reliable, and in most countries they are most readily available. Latex condoms can only be used with water based lubricants, not oil based lubricants such as Vaseline or cold cream as they break down the latex.

A small number of people have an allergic reaction to latex and can use polyurethane condoms instead.
Polyurethane condoms are made of a type of plastic. They are thinner than latex condoms, and so they increase sensitivity and are more agreeable in feel and appearance to some users.
