It seems that asexuals, or people with no interest in sex, have a lot of difficulty getting others to accept their disinterest.
In a world preoccupied with sex and finding sexual partners, where the media is awash with scantily clad women and advice on seduction techiques, those who're naturally indifferent to sex are still regarded as oddities - or suffering some sort of psychological problem.
An estimated one per cent of the population are thought to be asexual, and one asexuality website has over 50,000 members. There are plenty of couples who're perfectly happy without any love-making.
Yet whenever they "come out" to other people, sooner or later it'll be suggested that they're not really asexual, that actually there's something else going on.
They haven't found the right person, they're sexually repressed, they've been abused, they're secretly gay, it's a temporary phase, they're late developers. And so on and so on.
But why shouldn't people simply be uninterested in sex? Is that really so strange? It's just one sort of pleasure among a thousand others, and not everyone finds it essential. Life won't come to a grinding halt if a few people don't share the universal obsession.
And obsession it certainly is. Asexuals say they find it extremely tedious listening to workplace conversations that so often revolve around sex and the sexual attractiveness of workmates. They're mystified by the time and effort devoted to the topic.
But in our sex-sodden world, someone who never feels the tug of lust or the frisson of a naked body can be hard to comprehend. What, lacy underwear or rippling biceps do nothing for you? Nothing at all? What's WRONG with you?
