 Outlined here are the different types of barrier methods, spermicides, or coitus interruptus that must be used at or before every act of intercourse.Immediate contraception, like physical barriers, include diaphragms, caps, the contraceptive sponge, and female condoms may be placed several hours before intercourse begins (note that when using the female condom, the penis must be guided into place when initiating intercourse).The female condom should be removed immediately after intercourse, and before arising.
