What are they?
There are two types of condoms: male and female. Male condoms are made from very thin latex (rubber), polyisoprene or polyurethane. When used correctly during vaginal sex, they help to protect against pregnancy and sexually transmitted infections (STIs). When used correctly during anal and oral sex, they help to protect against STIs.

Condoms are the only contraception that protect against pregnancy and STIs.
How do they work?
The male condom is worn on the penis to stop sperm from entering the man's partner's vagina, mouth or anus. The condom has to be put on when the penis is erect, and before the penis comes into contact with the vagina, mouth or anus. To use a male condom, do the following:
Take the condom out of the packet, taking care not to tear it.
Place the condom over the tip of the penis.
If there's a teat on the end of the condom, use your thumb and forefinger to squeeze the air out of it.
Gently roll the condom down to the base of the penis.
If the condom won't roll down, you're probably holding it the wrong way round. If this happens, throw the condom away because it may have sperm on it. Try again with a new one.
After sex, withdraw the penis while it's still erect. Hold the condom on to the base of the penis while the penis is being withdrawn.
Remove the condom from the penis, and be careful not to spill any semen. Throw the condom away in a bin, not down the toilet.
Store male condoms in places that aren't too hot or cold, and away from sharp or rough surfaces that could tear them or wear them away.
How effective are condoms?
If used correctly and consistently, male condoms are 98% effective. This means that two out of 100 women using male condoms as contraception will become pregnant in one year.
Always buy condoms that have the CE mark on the packet. This means that they've been tested to the high European safety standards. Condoms that don't have the CE mark won't meet these standards, so don't use them.
Added benefits?
By preventing the exchange of bodily fluids, condoms help to protect against many STIs, including HIV. They come in many different sizes, shapes, colours, textures and flavours, so there will be one that suits you.
Whatever your age, even if you're under 16, you can get free condoms from community contraceptive clinics, sexual health and genitourinary medicine (GUM) clinics, some young people's services, and some GP surgeries. You can also buy condoms in pharmacies and supermarkets.

What else should I know?
Many people find putting on a condom an enjoyable part of sex, and it doesn't feel like an interruption.
If they're not used properly, male condoms can slip off or split. If this happens, practise putting them on so that you get used to using them properly. Or try using different kinds. There are lots of different sizes and shapes to choose from, so you'll be able to find one that suits you best.
If you're sensitive to latex, use polyurethane or polyisoprene condoms instead.
Although condoms (when used correctly) offer reliable protection against pregnancy, you need to use another method of contraception as well. This is to protect you against an unintended pregnancy if the condom fails.
If the condom splits or comes off, you can use emergency contraception to help to prevent pregnancy. This is for emergencies only, and shouldn't be used as a regular form of contraception. If you have been at risk of pregnancy, you have also been at risk of STIs so have a check up at a GP surgery, contraceptive clinic, sexual health clinic, genitourinary medicine (GUM) clinic or young person's clinic.
Male condoms are thin sheaths of latex (rubber), polyurethane (plastic), or animal tissue that are rolled onto an erect penis immediately prior to intercourse. They are commonly called "safes" or "rubbers." Female condoms are madeof polyurethane, and are inserted into the vaginal canal before sexual relations. The open end covers the outside of the vagina, and the closed ring fitsover the cervix (opening into the uterus). Both types of condoms collect themale semen at ejaculation (the release of semen during intercourse), and thusact as a barrier to fertilization. Condoms also perform as barriers to the exchange of bodily fluids between persons involved in a sexual act, whether male-to-male, male-to-female, or female-to-female contact.
Both male and female condoms are used to prevent pregnancy and to protect against acquired immunodeficiency syndrome (AIDS), genital warts and other sexually transmitted diseases. To accomplish these goals, the condom must be applied and removed correctly.
Male and female condoms should not be used together as there is a risk that one of them may come off. The male condom should not be snug on the tip of thepenis. A space of about 1/2 inch should be left at the end to avoid the possibility of it breaking during sexual intercourse. The penis must be withdrawnquickly after ejaculation to prevent the condom from falling off as the penis softens. So the condom should always be removed while the penis is still erect to prevent the ejaculate (sperm) from spilling into the vagina.
Male condoms made from animal tissue and linen have been in use for centuries. Latex condoms were introduced in the late 1800s and gained immediate popularity because they were inexpensive and effective. At that time, they were primarily used to protect against sexually transmitted diseases. A common complaint made by many consumers is that condoms reduce penis sensitivity and impair orgasm. Both men and women may develop allergies to the latex. Consumer interest in female condoms has been slight.
Male condoms may be purchased lubricated, ribbed, or treated with spermicide(a chemical that kills sperm). To be effective, condoms must be removed carefully so as not to "spill" the contents into the vaginal canal. Condoms that leak or break do not provide protection against pregnancy or disease.
If used correctly, male condoms have an effectiveness rate of about 90%, butthis rate can be increased to about 99% if used with a spermicide. (Several types of spermicides are available; they can be purchased in the form of contraceptive creams and jellies, foams, or films.) Benefits associated with thistype of contraceptive device include easy availability (no prescription is required), convenience of use, and lack of serious side effects. The primary disadvantage is that sexual activity must be interrupted in order to put the condom on.
Female condoms have a lower effectiveness rate against pregnancy; but, when used correctly and at every intercourse, during the course of a year they prevented pregnancy in over 75% of the women surveyed.
Checking the expiration date on a condom and examining it for holes before use are additional ways of enhancing its effectiveness. Because petroleum jellies, such as Vaseline, and other oil-based lubricants can weaken latex, any lubricants used during intercourse should be water-soluble.
