There's a lot of choice when you're buying condoms. What do you need to know to make a decision?
Material
Male condoms are usually made of latex (a type of rubber) but condoms made from polyisoprene are also available, which can be used by people who are allergic to latex. Female condoms are also made from a non-latex material called nitrile.
Quality
Male condoms come in different thicknesses, shapes and sizes, with or without a teat at the end to catch the sperm. A condom should carry one or both of the symbols below, a sign that it has passed certain tests and is of a decent quality.
Size
Penises come in different sizes so one size of condom will not fit all men. A condom that is too small can be uncomfortable and be more likely to burst, too big and it’s more likely to come off during sex. Sizes are stated on the packet; smaller condoms are marketed as ‘snug’ or ‘close’ fit, larger ones as ‘XL’. The biggest selection is online.
Thickness
Some people prefer to use thicker condoms for extra protection, especially for anal sex, but there seems to be no difference in breakage rates between thicker and thinner condoms.
No male condom should be used with oil-based lubricant as it makes them split. Silicone-based or water-based lube is needed instead.
Spermicide
Some condoms come covered with a spermicide, a chemical that kills sperm (the packaging will say if a spermicide has been used). Nonoxynol-9 is a spermicide that you may find on condoms. As spermicides might irritate the skin and increase the chance of infections, condoms without them are recommended if you have a choice.
Novelty
Condoms can come in different flavours (useful if you want to use them for oral sex) or with ribbed or shaped surfaces to increase sensation; even ‘glow in the dark’ condoms are available. These can be used for sex but check the packaging of any novelty condom in case it’s not recommended for sexual use.
Storage
Condoms should last about five years if stored correctly (a ‘use by’ date is on each wrapper). Keep them away from damp and heat (eg, radiators, lamps, direct sunlight). It’s not a good idea to carry a condom around in trouser pockets for a long time as it can get damaged by body heat and being sat upon.
