Obese Sammee Matthews has a condition which makes her so turned on by food she even scoffs doughnuts during sex.
Twenty eight stone Sammee has been diagnosed with sitophilia - an erotic obsession with food, in her case cakes and sweets.
The 42-year-old mum-of-two from Las Vegas, USA, says just the sight of a bakery is enough to send her weak at the knees and out of breath.
And her sexual fixation on sponge cake has contributed to weight gain which saw her tip the scales at 32 stone.
She said: "For some people oysters stimulate them, but for me it's anything sweet.
"I love cupcakes and cookies. It's the smell, flavour and texture that makes me feel aroused.
"When I can smell and see them I start to lose concentration, I stutter and obsess with it.
"I don't just look into a bakery and see a cute little cupcake - quite a few perverse things come to mind."

Sammee Matthews Diagnosed With Sitophilia
Sammee takes her obsession into the bedroom where she eat doughnuts during sex with her partner.
She said: "When I walk in to a bakery, the smell drives me wild and I have to call my boyfriend for sex.
"It's a huge turn on for me to be eating delicious cakes or doughnuts while making love. It gives me the most amazing orgasms.
"There's something about the smell, flavour and texture which makes it so thrilling."
However, her current relationship almost ended after she found out after two years that her boyfriend was married.
She said: "It was a huge shock but I can't walk away from this guy.
"He tells me no one will love me the way he does, and I believe him.
"We're trying to keep some space between us but it's made me feel insecure and given me a fat girl stigma."
Sammee, single mum to Sabrina, 22, and Anna 16, began putting on weight as a child and by the time she was 11 she weighed 14 stone.
She fell pregnant at 18 with Sabrina but split with the dad before she was born and was celibate until she met Anna's father but they broke up two years later.
By that time her weight had reached 23 stone but she continued to gain.
At her heaviest she was 32 stone, making her virtually housebound and needing assistance from her daughters to dress and eat.
But after losing four stone through a crash diet, she became a BBW model and began making money through pay-per-view webcams.

Today 5ft 1 Sammee's BMI is 84 - while the healthy range is 18-25 - and says her new partner, who weighs 14 stone, understands her fetish.
She now runs a strip club night for overweight women called Thick Sundaes. She said: "I know my body is damaged because of my weight, I have no cartilage left in my knees.
"Some days my feet swell up so much my daughter has to put my socks on.
"I take a lot of pills to help my muscles relax and to take away the pain.
"But I'm making the most of my situation by putting on nights which empower other larger women and hopefully change perceptions of how fat people are viewed."
