This is how I see it. I don‘t have any evidence to back this up, so it‘s only what I observed. Because of my work, I see many people of different ages. The only couples I know which are really strong couples, a real team, are the ones who were their firsts (maybe seconds). All of them became a couple a a young age (17-19). These are the only ones where there‘s a visible strong bond. Of course there are other couples where it works but if you see tham and here them talk it‘s never in the same way.

I don‘t know why this is.

I talked to many people of all ages, male and female, about this issue. Heres their ideas. Maybe emotional scarring lessens current feelings? Maybe people see someone who has been with others not as a price and therefore don‘t put in as much effort? Maybe as soon as someone has casual sex, the ability to bond suffers extremely?

I don‘t know what it is. All I know is that I have observed that kind of stuff in many cases.

To make clear; none of all the people were either extremely conserve or religious.
