What is a condom and how does it work?
A condom, also called a prophylactic or rubber, is a thin sheath that fits snugly over an erect penis to act as a barrier. The closed end of the condom catches the semen, so that it cannot pass into your partner at the time of ejaculation. There are many types of condoms available: latex rubber, polyurethane, lambskin, lubricated, and spermicidal. Most condoms sold in the U.S. are latex condoms which come in a variety of textures and colors. Latex and polyurethane condoms are the only condoms which prevent transmission of HIV. Condoms should be used for all acts of vaginal, anal or oral sex (on a man) to help prevent pregnancy and/or the transmission of STIs (sexually transmitted infections). Condoms are available in many varieties: colors, flavors, shapes, textures, lubricated, non-lubricated, with or without spermicide–almost any type to meet different needs. You may want to experiment with the type of condom that is most satisfactory to you and your partner.
