Using condoms

Condoms are one of the most widely used contraceptives amongst the 18-30 age group and, when used appropriately, can be very effective. To protect yourself and others against STIs it's a good idea to carry a condom with you if you think you might have sex. Below are a few points you might like to consider:

Expiry Date -

Although they have a long shelf life, it is important to check the use by date stamped on the wrapper. You should also ensure that there is a BSI Standard Kitemark or CE quality stamp on the condom.

Storing condoms -

Do not keep condoms in your wallet, or pockets for long periods of time. The heat and friction they experience can degrade the condom making it more likely to break. One of the best places to store condoms is in a bedside draw, out of direct sunlight and away from heat sources.

Allergies -

If you are allergic to latex you can buy Avanti condoms (which are hypo-allergenic and not made of latex). CUSU now stocks these (see the 'where to get condoms' page).

Novelty condoms -

Although amusing, if there is no Kitemark assume the condoms will not protect against STIs or pregnancy. Take a look at our http://www.cusu.cam.ac.uk/welfare/sexualhealth/condomsafetytests.htmlwww.cusu.cam.ac.uk/welfare/sexualhealth/condomsafetytests.htmlbefore you use any condom.

Lubricant -

Condoms are easily damaged by oil-based lubricants which degrade the latex and increase the likelihood of rupture. Instead, water-based lubricants such as KY Jelly, or thos available from CUSU, should be used.

Before intercourse -

Almost all of the times things go wrong with condoms it is because they are being used incorrectly.

  • Wait until the penis is fully erect before putting on the condom. This will make it less likely that the condom will slip off.
  • Only ever use one condom at a time. Putting on two condoms (one on top of the other) does not increase security, in fact all it does is make it more likely both condoms will come off or that both will rupture.
  • Never re-use condoms.
  • If you have started to put the condom on the wrong way round throw it away and use another one.
  • Always squeeze the teat at the top of the condom to remove air before putting it on. An air pocket in a condom is more likely to rupture.

After intercourse -

Withdraw the penis immediately after ejaculation, ensuring that the condom does not slip off and release its semen. If you're living in college accomnodation you are probably asked to wrap the condom in tissue before throwing it away.

Extra-safe or Extra-strong condoms

'Extra strong' or 'extra-safe' usually means extra thick, and up till about three years ago it was common practice to recommend the use of 'extra strong condoms' for anal sex, given the extra friction. However the general consensus then shifted (partly based, on an Australian study of condom failure) to the view that there was no evidence that extra thick condoms provided extra protection, and that the key factor was correct condom use, enough lube, putting the condom on correctly, as mentioned above. There is however no evidence that extra thick condoms are any more likely to fail (though they make give someone a false sense of security if you don't practice all the other 'good condom use' stuff). Sometimes 'extra-safe' condoms also have extra spermicide has been added (it should say on the packet), which isn't recommended as it can cause irritation/inflammation of the vagina which facilitates the transmission of STIs including HIV.
