Condom

What is a female condom?

A female condom is similar to a male condom, but is wider and is worn inside a woman's vagina rather than over the penis. It is made of polyurethane rather than latex. The condom has two rings - the ring at the closed end of the female condom is pushed up inside the vagina, while the ring at the open end surrounds the entrance to the vagina. The man's penis is guided into the condom through this ring.

If I use a condom I seem to lose my erection…

It is a good idea to get some condoms before having sex and practice using them. That way you can get used to the feel of condoms and putting them on, which should help you feel more relaxed about using them when having sex and less likely to lose your erection.


Can you use a condom under water?

If you are going to use a condom under water it is important that you put the condom on before you get into the water. Also, if the water contains chemicals such as chlorine, or additives such as soap, bath oil or bubble bath then this may affect the latex.


Are condoms effective against HIV and other STDs?

Condoms are very effective at preventing HIV transmission, and will also help to prevent the transmission of any other infection that's spread through semen or vaginal fluids. However, they are only effective if they're used properly every time you have sex.
