Condoms come in all shapes, sizes, and materials. Here are some characteristics to consider when buying condoms.
Size. The standard size will fit most men. Extra-large condoms are available, as well as "snug" sizes that are a little smaller and fit tighter than the standard size.
Shape. Some condoms come with a nipple in the end to hold the fluid when the man ejaculates. Others have a rounded end.
Thickness. Extra-strength condoms are available. These are stronger and are especially useful for rectal sex and for men who have problems with condom breakage. Extra thin condoms also are available, but these are not recommended because they may break more easily.
Lubrication. Many condoms come pre-lubricated. This lubrication can be a substance that kills sperm (spermicide) and many disease-causing germs. Lubrication may give some extra protection in preventing pregnancy, especially if the condom breaks. Lubricated condoms taste bad and are not recommended for oral sex.
Flavored. These condoms are meant for the male to wear when receiving oral sex. They are not lubricated and have a mild flavor (usually mint).
Color. Condoms come in many colors. The color of the condom doesn't make it any more or less effective.
