The two main types of condoms available in Australia
The external condom is a thin pouch that is usually made of latex (rubber) and also available in polyurethane (plastic) or polyisoprene (synthetic rubber). You put it on an erect (stiff) penis or sex toy before it enters the vagina, mouth or anus during sex.
The internal condom is a soft pouch made of nitrile (synthetic rubber), that has two flexible rings at each end. It is inserted into the vagina or anus before having sex.
