Want the secret to a happy marriage? Don't have sex before the wedding
The Beckhams say that quality time is the secret behind their happy marriage, while Michael Douglas once credited Viagra with the secret to his.
But, according to a new study, it is couples who delay sex until after the wedding that enjoy a stronger relationship later in life.
Scientists at the School of Family Life at Brigham Young University, in Utah interviewed 2,035 married people about when they first had sex with their partner.
Analysis of the results showed that couples who waited until marriage before having sex enjoyed a much healthier relationship with their partner than those who started having sex in the early part of their relationship.
In particular, relationship stability was rated 22 per cent higher, relationship satisfaction was 20 per cent higher, quality of sex was 15 per cent better and even communication between partners was 12 per cent better.
For couples who became sexually involved later in their relationship, but before marriage, the benefits were about half as strong.
The research supports the decisions made by celebrities such as actress Lisa Kudrow, who had not had sex before she married her advertising executive husband Michel Stern, and pop stars The Jonas Brothers.
While it is common for couples to explore their sexual compatibility before making a long-term commitment, the researchers argued that too much emphasis is put on the physical side of a relationship, and too little on trust, loyalty and commitment.
Professor Dean Busby, who lead the study, said: 'Most research on the topic is focused on individuals' experiences of sex and not the timing within a relationship.
'There's more to a relationship than sex, but we did find that those who waited longer were happier with the sexual aspect of their relationship. I think it's because they've learned to talk and have the skills to work with issues that come up.'
Mark Regnerus, author of Premarital Sex in America, echoed Professor Busby's opinion.
He said: 'Couples who hit the honeymoon too early - that is, prioritise sex promptly at the outset of a relationship - often find their relationships underdeveloped when it comes to the qualities that make relationships stable and spouses reliable and trustworthy.'
Given that religious beliefs often play a role for couples who choose to wait, the researchers took any influence of religion into account.
'Regardless of how religious a couple are, waiting helps the relationship form better a communication process and this improves long-term stability and relationship satisfaction,' added Professor Busby.
