The duo, who themselves have been married 36 years, have spent the past five decades studying love and what makes it last 

John began by referencing the work of Chrisanna Northrup titled The Normal Bar, which analyzed 70,000 people across 24 countries 'to discern what's different about people who say they have a great sex life and people who say they have an awful sex life.'

He claimed that the findings were 'the same across the whole planet' before reeling off a whole host of differentiators.

'There are really about a dozen things that people do and have a great sex life - saying, "I love you" every day and meaning it is one of them, giving compliments, romantic gifts, having a lot of touch,' John shared.

He then turned his attentions to cuddling, explaining: 'Of the people who don't cuddle, only four per cent of them said they had a great sex life. Ninety-six per cent of the non-cuddlers had an awful sex life.

'Touch is very important important - even physical touch and public affection was a big thing.'

John stated that the romantic connection went beyond just 'kissing or what happens in the bedroom.'

Nonetheless, he went on to delve deeper into the practice of kissing.

'There has been research on just kissing and it turns out that in not every culture do humans kiss but in the ones they do kiss it is very powerful, very erotic for most couples and it's a nice gateway into eroticism,' the expert dished.

He then quoted a 10-year German study that found that 'men who kiss their wives goodbye when they leave for work live something like four years longer than men who don't.'

John recommended opting for a six-second kiss which had 'much more potential than a peck on the cheek.'

'Oxytocin gets secreted with a 20-second hug or a six-second kiss you're both secreting oxytocin and that creates a sense of psychological safety and connection and bonding,' he explained.

Previous guests on Steven's podcast have also dished on the ultimate relationship red flag and the truth about having the 'perfect body.'
