A woman must visit her doctor to be fitted for a diaphragm or a cervical cap. Using a diaphragm, cervical cap or contraceptive sponge may increase the risk of urinary tract infections in some women. Some women have allergic reactions with these methods.

Are condoms a good choice?
Yes. Condoms aren't expensive and are widely available. Condoms can be combined with other methods of birth control. Condoms are an especially good choice if you or your partner are also having sex with other people or if either of you have had sex with other people in the past.
Of all the barrier method options, condoms offer the most protection against STIs. Using a spermicide with condoms can offer better protection against pregnancy, but it may not increase your protection against STIs. Spermicides containing nonoxynol-9 can cause genital irritation and may actually increase your risk of catching an STI.
Female condoms aren't as effective as male condoms, but they may be a good choice if a man won't use a male condom.
