Amanda McLaughlin, 23, from the United States, has lived with the problem of persistent arousal for 10 years.

She has to beg her fiance JoJo for sex every day to relieve her symptoms.

The condition, called persistent genital arousal disorder (PGAD), causes pain in her legs and pelvis that is so bad she is unable to work and rarely leaves her home.

Now Ms McLaughlin has spoken of her ordeal as part of a documentary for BBC Three’s Living Differently.

It’s not fun to be aroused all the time,” she said. “It feels like you’re about to orgasm and then it never goes away.”

Ms McLaughlin’s symptoms began when she was just 13 years old but she was not diagnosed with PGAD until six years later.

Her mother, Victoria, admitted that she and her family did not understand her daughter’s condition at first.

“When she first became sexually active, she was having sex a lot,” she said. “My whole family just thought she was a wh**e.

“I doubted her completely — I still feel guilty” Victoria is now very supportive of her daughter, as is JoJo.

Amanda said: “Relationships are really hard to keep with this problem. But he never once has judged me, he never made me feel bad about working. It was love at first sight.”

She added that her condition affects the couple’s sex life ‘tremendously’.”

Amanda currently takes 30 different types of medications to ease the pain caused by her condition.

She also uses ice ‘inserts’ to ease her pelvic swelling.

Assistant professor of neurology at Michigan University, Dr. Priyanka Gunta, who is currently treating Amanda, said: “Because it’s such a rare diagnosis and there’s been such little research, we don’t know exactly what causes it. We suspect it’s multi-factorial.
