While there can be dangers, we feel secure enough in our relationship that I have been doing this for a few years. Quite early after we started swinging, my husband would leave me alone in the room with the other man after a threesome, letting the two of us play some more. However, more recently, I have traveled alone, even out of town, to meet up with friends. (This is only for men whom I know well. I would never meet a new man alone.)
