Helen Morfitt, 56, started life as Leslie, and is due to marry Felix Laws, 46, formerly Katy, in September.
Between them, the couple has already been married four times, and Helen has eight children and Felix two from their previous relationships.
They will officially change their gender on their birth certificates, allowing them to get married, with a date set for 13 September, the date both had their sex change operations, albeit seven years apart.
Helen told the Daily Mirror: "We've been through a lot over the years and had tough times transitioning from one sex to another, but we've now found each other and that's all that matters.
"I've been married three times before but this time I know it's for real because I know I'm the right sex this time."
Felix added: "We're just like any other couple - including in the bedroom. Neither of us has any complaints on that score."
The couple met in 2008, when Felix visited a doctor about the possibility of having a sex change operation. The doctor referred him to a transgender support group run by Helen.
"As a child my friends were playing with dolls and prams but I wanted to climb trees, play football and get muddy," said Felix.
"Even sitting down to go to the toilet felt wrong. But it was the 1970s and you didn't have those kind of thoughts back then."
He got married as Katy at 21 and soon had two children.
