Can you live a love story without having sex?
A British study of nearly 2,000 people found that about 18 percent of respondents under the age of 30 had sex less than 10 times last year.
The study, published by Mamasnet, a website for parental counseling, and Grantsnet, a website on older people over the age of 50, said the rate was 29 percent for all ages.
The supervisors of the study met three couples, who live love stories, and fall into this category.
Amanda and Steve married six years ago.
"There is no sexual life between us at this moment because of me," Amanda, 35, told the BBC's Victoria Derbyshire program.
"I'm tired all the time because my job requires many tasks, as well as the tasks of the house.
The couple, looking at each other and laughing and their 22-month-old son, Elliott, walks happily around the room, causing their sexual life now every six weeks.
"It does not happen to have sex in the day or afternoon with a child around us," says Steve, from London.
"Even if you make him sleep for two hours, you're like someone who says, 'Maybe I should do anything else, take the opportunity and sleep some time.'"
Martin Barrow, a sex consultant and therapist, says it is not just about parents who have a low appetite for sex.
"We seem to be seeing a larger number of people becoming dissatisfied with their sexual relationships," he said.
"Whether there is a cultural shift to people who feel more comfortable talking about sex or whether there are people who have sex at a lower rate, I'm not sure, you can have a successful relationship whether it involves sex or not."
"Some people do not need sex to feel happy, others are on the contrary," he said.
Jacob and Charlotte, both 23, live a great love story, but sex is not part of their relationship.
"We have been living together for four years, we have not had sex in three years and we do not intend to," says Charlotte.
Charlotte is described as having no sexual desire, unlike Jacob.
"We tried to have sex for the first six months to find out what was going on - in fact, it did not make us happy."
"Jacob does not want to have sex with someone who does not want to have sex," she said.
For some men, this is a clause that breaks an agreement between two parties, but it is not so for Jacob, who said, "I have a wonderful relationship with a wonderful human being, there are other ways to show passion."
"I do not think I'm able to talk to anyone about it without implying that I do not have sex," Charlotte says.
"It's really sad that some people give priority to sex more than happiness," she said.
Tom and Steve, from Bristol, live together four years ago and married last year. But they did not have sex at all.

They describe themselves as a loss of sexual desire, and talk about their first encounter, when they slept together, as "one of the best nights, we were together and nothing happened."
Tom believes that society has become increasingly sex-oriented, but that "does not reflect that people are becoming increasingly sex-loving."
"There are pressures for sex, and people may force themselves to have more sex normally."
Tom and Steve say people are surprised when we tell them we have never had sex and ask how you love each other without exercising it.
"If it is possible to have sex without love, then why is there no love without sex?"
Martin believes that how sex in relationships "makes the relationship abnormal".
Some couples can "reach the highest levels of intimacy without having sex," he says.
Others believe that how much sex is exposed to tidal waves and is affected by things such as having young children, work, fatigue or illness.
Amanda says communication with Steve was key to having a healthy and strong relationship without having sex regularly.
"You do not feel very disappointed, because it happens to all of us," she advises new parents who live the same way.
"We'll practice it again," she laughs as she looks at Steve
