Men often leak a few drops of semen before ejaculating, without realizing it. They can also act as a contraceptive, but for increased peace of mind, it would be safer to use another method of contraception as well.
Condoms can break or come off during sex.
There can therefore be the risk of pregnancy as well as infection. If you need advice about contraception, telephone your nearest Family Planning Clinic or talk to your family doctor. Condoms may be supplied free at local Family Planning Clinics and some Hemophilia Treatment Centers. They are also available from drugstores, some grocery stores and other retail outlets or from mail order advertisements in newspapers. They are very easy to get and inexpensive.
