Questions from a Married Punjabi Couple

We are a Punjabi couple from Delhi, and we’ve recently become curious about the swapping lifestyle. During sex, my partner and I sometimes talk about being with other people — for example, she might mention being with someone else, or I might express a similar curiosity. This interest has made us think about the idea of swapping, but we’re not sure if it’s the right path for us. We’re just exploring it for now. Have any married couples tried it? Is it safe? Does it lead to trust issues? Any real swapper couples who can share their experiences?
