Jenny-Anne Bishop and Elen Heart decided against sex-change surgery because of health risks at their age
Jenny-Ann, 62, who used to be Paul, and Elen, 65, who was once Alan, think they were born in the wrong bodies.
The couple pair, who have five children between them, take female hormones, wear fashionable dresses, lipstick and mascara, and curl and style their hair and wigs.
"Our relationship is hard to define," says Jenny-Anne who was married for 35 years before she met Elen.
"We're not exactly lesbians, but people might use that word.
"To us we are just two transgender people who love each other."
Now retired, they have set up home together in Clwyd, Wales, and say they plan to have a civil partnership and grow old together.
"Our children have grown up and we are divorced so it's time for us to be who we really are," says Jenny-Anne.
"Sometimes people call us bloody trannies or stare in a funny ways.
"Our relationship may be hard to understand because we have male genitalia but we live as a lesbian couple.
"People sometimes say we're gay men but we don't fit into that category – if you want to define us we're 'trans lesbian'."
The couple share a bed, are very tactile with each other and say they have a good sex-life.
Elen added: "We enjoy each others company and go for lovely walks in the countryside, or do the gardening or housework together."
