To commemorate international AIDS awareness day on 1st December 2005, a 67-metre pink condom was made and placed over the Obelisco (obelisk) in Buenos Aires, Argentina.

On 1st December 2003, Benetton in collaboration with ACT UP Paris placed a giant condom (22 metres high and 3.5 wide) on the obelisk in Place de la Concorde in Central Paris.

Manufactured by Church & Dwight Inc., Co., Trojan Magnum XL condoms are 30% larger than standard condoms.

Many birds do not have penises, and mate by touching genital openings -- called a "cloacal kiss". But some species of duck and ostriches do have a penis.

The longest bird penis discovered belongs to the Argentine lake duck (Oxyura vittata), measured at around 42.5cm, an astonishing dimension matches the length of an adult male, and compares to the length of an ostrich penis. If the Argentine lake duck were human, we could boast 5 - 6-foot penises!

Clitoris size has only rarely been of importance in human society.

A few communities -- Ford and Beach mention the Easter Islanders -- have favoured the large clitoris and some natives have tried with varying degrees of success to enlarge this organ in their girls. For the most part however, with a prevailing indifference in the nineteenth-century and early part of the twentieth-century to sexual arousal in women, the clitoris has been neglected. Needless to say, it varies in size.

Pubic hair, short and curly in most of us, sometimes grows to quite extraordinary lengths.

The lovers are having sexual intercourse, an episode that illustrates the kind of steady nerve on which the 18th century Rajput military castes prided themselves.

It all depends what you mean by lovemaking. Does it count if you knock off for a sandwich and a drink and then start again? No agreed ground-rules have been established. Anyway one figure that will do for a starter is the fifteen hours recorded by Mae West in her autobiography - a man called "Ted" apparently made love to her for this length of time: He later said that "he was both astounded and pleased at his own abilities."

The idea of orgasm as climax suggests that it is soon over, and this is indeed true. At the same time a single orgasm can sometimes roll on and on with the man - or more likely the woman - carried along on waves of bliss. According to Fisher the typical female orgasm lasts from 6 to 10 seconds. In a few extreme cases in the various samples, it was reported that orgasm lasts "more than 20 seconds". With the general spread of human ability we may expect a record orgasm to last for around half a minute!

For some purposes it may be desirable to maintain an erection for a long time. It is clear that periods of up to an hour are not uncommon, and that if the penis is in the vagina for this time then maintaining an erection is not difficult for some individuals.

Kisses between men and women usually last for a few seconds. Kisses lasting minutes are unusual, kisses lasting hours quite remarkable.

There is a type of kiss called "maraichinage" - after the Maraichins or inhabitants of the district Pays de Mont in the Vendee (Britanny) which quite literally lasts for hours. In this type of exchange the couple mutually explore and caress the inside of each other's mouths with their tongues "as profoundly as possible." Maraichinage has been recommended as a "real antidote against depopulation."

Cary Grant has been an immensely successful romantic lead in Hollywood for more than thirty years. No other male actor can compete with this record. One of his best known films - "Holiday" appeared in 1938; yet still Cary Grant plays successful romantic leads.
