A condom has a ring (6) adjacent the open end (1) for expanding the condom to a maximum diameter to maintain the open end outside the vagina, and a tubular portion (3) extending between the ring and the closed end is of a size to form a loose fit around the penis and is formed with a series of circumferential grooves (5), e.g. 3 to 5 grooves around 0.8 cm wide and 1.0 cm deep, so that the condom naturally folds in a bellows like manner for the condom to collapse to a substantially flat condition prior to use.
