The alleged toe-sucking exploits of David Mellor MP and those famous photos of Fergie on a sun-lounger introduced foot fetishism to those who had never heard of it before. When Liz Taylor married Larry Fortensky, who is 20 years her junior, a resounding “Aaah!” was heard in Fleet Street.Sexual outlaw rating: 1/10.FETISHISMFetishism is often confused with S/M, but it is a mistake to assume that all those who enjoy dressing up in leather and rubber, or who worship footwear, are necessarily sado-masochists. Older women who take toy boys are less respected.Numbers game: The National Survey suggests that men are slightly more likely to have younger partners than woman: 28.3 per cent of men and 9 per cent of women had partners who were six or more years older.Legal status: Legal.Media interest: Fitful. Body piercing – a staple of the fetishist’s diet – has become hugely popular.Numbers game: London’s annual Rubber Ball attracts 2,000 revellers Anne Summers is a national institution.

Only 1 per cent of our respondents (full survey results on pages 6 and 7) defined themselves as bisexual; but then 13 per cent didn’t define themselves as anything.Legal status: No legal prohibitions as such, but see Homosexuality below.Media interest: Confused. EastEnders’ Pam St Clement, outed as a lesbian several years ago, now describes herself as “bisexual”. For many, bisexuality is just homosexuality by any other name But bisexuals themselves proudly assert a distinct identity.
