In various cultures, older men and younger women often seek one another for sexual or marital relationships.
A study released in 2003 by the United Kingdom's Office for National Statistics concluded that the proportion of women in England and Wales marrying younger men rose from 15% to 26% between 19.
"My fiance is 30 years older than me," says Tirzah Allen.
While she waits for people to pick their jaws up off the floor, she explains the benefits of marrying someone old enough to be her dad.
But what I'm trying to say is, more people still think that a romantic relationship is ideal when it's between an older man and a younger woman.
Specifically, four years and four months older, which was the average "ideal" age gap as reported by a survey of 2,000 adults.
Concepts of these relationships, including what defines an age disparity, have developed over time and vary among societies.
The study was originally published in September 2014, and a writer broke down some of the stats and brought the news in an easier-to-read format.Here are 17 celebrity couples who chose to love each other for who they are and not what song was popular the year their partner was born.Research from Emory University shows the bigger the age gap in a marriage ... Now, at first that might sound like it makes sense.While slightly less than half of people said there was no ideal age gap (good call, sensible people), 33% of women wanted a guy up to seven years older than them, while only one out of a hundred women preferred a younger man.Not that I have anything against dating older guys, but here's some afternoon uggghhh: Financial stability was one of the biggest reasons women cited for preferring older dudes, since 55% of women said they couldn't afford rent or mortgages on their own. Most of the guys I've dated have been my age to just a couple of years older, but sadly for poor old me (literally), none of them have provided any financial stability so I don't think I'd call that a motivation.
