'When he emailed me a photo, I thought what a handsome and sexy man he was before pinching myself – he was my grandson!'Confused, Pearl talked to a friend, who told her about an article she'd read on Genetic Sexual Attraction (GSA), which occurs when close relatives meet as adults and are attracted to each other.
'I could now understand my feelings and realise they weren't wrong,' Pearl says.
In 2006, Phil met his grandmother for the first time.
'From the first moment that I saw him, I knew we would never have a grandmother-grandson relationship,' Pearl remembers happily. 'For the first time in years I felt sexually alive.'
Phil admits that he had the same feelings towards Pearl.
'I wanted to kiss her there and then,' he says. 'My feelings were overwhelming.'

They sound a bit to me.
