From Swapping to Cuckolding: Is this your journey?

I have been in talks with a number of couples from India and outside regarding how they got into this cuckolding (Or threesome for some people). And to my wonder, many of them were initially into swapping partners or swinging. They had no intension to penetrate into a threeway but soon after they realized the real power dynamics and the true essence, they eventually ended up being into this. And that's not the story for one or two couples, that's something becoming (Or has become) common. What's your take?
