Mature dating and relationships
As for same-sex couples, there’s very little research.Some suggest a lack of, or a reduced pool of, suitable age-similar mates may bring about same-sex coupling with large age differences.With more women working, in higher positions and being paid more, they no longer have such a reliance on men for resources.So fewer women will prioritise resources when looking for a mate.These effects appear to apply to heterosexual and same-sex couples.So the negative outcomes for age-gap couples seem to reside not in problems within the couple, but in pressures and judgments from the outside world.
But some studies find the relationship satisfaction reported by age-gap couples is higher.
In some non-Western countries, the average age gap is much larger than in Western countries.
For example, in some African countries about 30% of unions reflect a large age gap. And do couples with large age gaps experience poorer (or better) relationship outcomes compared to couples of similar ages?
Many of the reasons proposed for age-gap couples have been largely rooted in evolutionary explanations, and focus on explaining older man-younger woman pairings.
From this perspective, it’s thought men’s preferences for younger women and women’s preferences for older men relate to reproductive fitness.
