What Lytton didn't know was that the consequences of that love would plunge him into the most devastating crisis of life. The situation is far worse than that. Despite forming a warm friendship with Lytton, and meeting him several times a year either abroad or in Britain, Meadows, a divorcee, has never shared his feelings. Irritated and, at times, angry with his outpourings of affection, she recently emailed him curtly to think of her as "just a casual friend".
Unable to reconcile himself to her indifference, Lytton's subsequent depression and sense of rejection, and the continuing compulsion to declare his feelings, are no different from the irrational fixation and emotions that mark any young adult's first major infatuation.
In the circumstances, Lytton's new-found love was doomed to be a nonstarter. He is a married man Genetic sexual attraction statistics 66, semi-retired, with grown-up children and grandchildren.
The story might be relatively straightforward, Genetic sexual attraction statistics there may even have been a happy ending of sorts had he merely fallen for a woman half his age or abandoned his family to start a new life in another country.
Instead, his love for Meadows represents society's most abhorrent taboo. She is his younger sister, adopted as a baby shortly after the death of their mother from an illness contracted after the birth, when Lytton was two.
Although Meadows had no idea she had a brother, Lytton, who was raised by his stepmother after his father's death during the second world war, had always known of her existence, but waited until to begin searching for her.
The party at which they met had been organised by Lytton, with the help of his wife children, as a celebratory reunion after he had tracked down his year-old sister in Durban.
Even in front of my wife, I made no attempt to hide my adoration, I just buzzed whenever she was around. It was as if no one else existed.
The two biggest mistakes I made were deluding myself that I could become all-important in her life, a brother and a surrogate lover, even though she didn't desire me, and then believing I could control and resolve the problem by myself. When we met, Lytton brought with him several large files bulging with four years' correspondence, mainly email printouts, to and from Rita. A tall, white-haired and articulate man, he has recorded every emotion, thought and incident involving his sister since their reunion.
Photographs taken on his trips to South Africa, and on her visits to Scotland, show a vivacious and elegant redhead, seemingly little older than From the sharp intake of breath as he begins reading Genetic sexual attraction statistics from his correspondence, it is clear that his feelings are still raw. Letters written shortly after their reunion begin with such endearments as "my special girl", "goddess", "darling miracle", "my princess". Declaring that she "walks on water", Lytton confesses how much he misses and thinks of her, miserable at the Genetic sexual attraction statistics between Edinburgh and Durban.
The places they have visited together are described as "sacred shrines". But a persistent undercurrent of uncertainty and despair runs through almost every message, as he urges her to write more frequently and to reveal her own feelings. You illuminate my life But how important am I to you? Do you feel affection for me?
Far worse Genetic sexual attraction statistics the pain, he says, are the shame and guilt. Every line oozing with obsession. I mean, what normal brother ever spoke to a sister in this way? How can a man approaching 70 experience emotions usually attributed to a screwed-up adolescent? He then produces a diary, one of several in his briefcase, labelled The Journal Of An Emotional Junkie, and offers to lend Genetic sexual attraction statistics to me.
He started to keep the journal eight months ago, after discovering that his sister had begun a relationship with a year-old South African banker. He became intensely jealous - an emotion, he stresses, that is virtually alien, and therefore deeply shameful, to him.
In one revealing passage he fantasises about his sister having sex with her new lover. Once she left England, I visualised her gyrating around a pole, in a G-string, her boyfriend watching lustfully on the bed.
Although this is the first time Lytton has told any of this to a stranger, he feels that, by doing so, he is beginning to control and resolve the situation.
Perhaps my experiences can help anyone else in a similar predicament, let them realise they are not alone, that they aren't going mad and haven't turned into some sick, perverted individual - all of which I thought until very recently. In the past year, Lytton says, he came close to wrecking his marriage, having a complete nervous collapse, even committing suicide. What saved him was his sister's emotional detachment, his wife's extraordinary patience and understanding - and, most crucially, learning about a little-known phenomenon called genetic sexual attraction GSAincreasingly acknowledged by post-adoption agencies to be a common feature of reunions Genetic sexual attraction statistics blood relatives who have never before met.
The emergence of GSA both in the US and the UK coincided with the relaxation of adoption laws in the mids, which gave adopted children easier access to their records and led to an increase in the number of reunions between adoptees and their blood relatives. The unexpectedly high number of reported cases of men and women struggling with sudden and terrifying emotions a reunion has surprised and perplexed most post-adoption agencies.
Growing awareness of its potentially devastating implications, especially in cases where relatives embark on a sexual relationship, has prompted some organisations to warn all clients attempting to trace a relative about the phenomenon, while also training counsellors to recognise the warning signs and to help adoptees and their families cope with the damage.
These may sound like important and timely advances but they don't, in fact, add up to much. Because of the revulsion aroused by incest, and the stigma attached to anyone who admits experiencing GSA - let alone those who embark on sexual relations with a parent or sibling - the condition remains obscured by Genetic sexual attraction statistics, tainted by smutty innuendo, under-reported by sufferers and, worse, virtually ignored in academic circles.
Although, occasionally, a story involving GSA is given predictably lurid tabloid coverage, ignorance prevails. Why GSA occurs only in some reunions, whether certain people are more predisposed to GSA than others, or whether it manifests itself differently between parents and children or siblings, is simply unknown.
Above all, GSA raises serious questions about what factors influence sexual attraction: The lack of any serious scientific research is especially disturbing in view of the growing number of reunions between adoptees and their birth parents, and the prospect of many future reunions between children born through IVF involving sperm and egg donors.
Gonyo, the non-academic who originally "outed" GSA in the s, has written the only book Genetic sexual attraction statistics the subject. In it, she suggests that romantic love and erotic Genetic sexual attraction statistics may be the delayed by-product of "missed bonding" that would have normally taken place between a mother and her newborn infant, or between siblings had they not been separated by adoption.
It may become sexual, or it may not. Gonyo's reputation as the world's leading GSA "expert" came about largely as a result of her own experience of strong sexual attraction, when, in and aged 42, she was reunited with her adult son 26 years after she had given him up for adoption.
