A mother who was reunited with her son after giving him up for adoption more than 30 years ago says the pair are now in love and are trying for a baby.
British-born Kim West, 51, and her son Ben Ford, 32, who lives in Michigan, have been in a relationship since they met in 2014.
West, who grew up in Islington, London, became pregnant while studying in California and after giving birth to her son aged 19, gave him up for adoption.

But ever since the pair were reunited in January 2014, when Ford was still married to his wife Victoria, they realised they were attracted to each other.
Now two years on, Ford has split from his wife in order to be in a relationship with his mother, in what they describe as 'Genetic Sexual Attraction'.
And now they plan to marry and are even trying to have a baby together.
West, who works as an interior designer, told New Day: 'I know people will say we're disgusting, that we should be able to control our feelings, but when you're hit by a love so consuming you are willing to give up everything for it, you have to fight for it.
'It's a once in a lifetime chance and something Ben and I are not willing to walk away from.'
Ford first got in touch with his biological mother in December 2013, while living with his wife in Colorado, as we wanted to know more about his birth parents. 
They arranged to meet up and the couple grew close, and eventually shared their first kiss after enjoying a bottle of champagne in a hotel.
Soon after, Ford, a freelance computer coder, left his wife Victoria after realising he had fallen for his mother and moved to Michigan, where they met with another GSA couple.
He told New Day: 'When I met Kim, I couldn't think of her as my mum but instead as a sexual being. I had seen a therapist at an adoption support group and had learnt about the GSA phenomenon.'
Now the couple are planning a special wedding and hope to have a baby together. They also say they will consider surrogacy, if they are unable to have a biological child together.

Genetic sexual attraction is a seldom-talked about phenomenon that frequently occurs between adoptees and their long-lost parents.
It describes feelings of intense intimacy between two relatives who have been separated during the critical years of development and bonding, and then meet for the first time as adults.
Essentially strangers, when an adult-child and their biological parent finally meet, the brain struggles to associate each other as family.
Instead, they become captivated with one another, sharing similar physical features, likes and dislikes, which is coupled with complex feelings of intimacy. This can lead both parties to express their emotions sexually.
The phenomenon was first identified by Barbara Gonyo in the Eighties, after she a wrote book called I'm His Mother, But He's Not My Son, which recounted her personal story of reuniting with the son she placed for adoption at 16.
GSA is rare between people raised together in early childhood due to a reverse sexual imprinting known as the Westermarck effect, which desensitizes them sexual attraction. Experts believe that this effect evolved to prevent inbreeding.
