So if poly means everyone knows about the other and consents to what’s going on, my question becomes: at what point does it go from just a poly relationship to cuckolding? In my case, I am supportive and know what’s going on. My job requires me to be gone about three days at a time. To be honest, I don’t always have the drive to satisfy her sexually. She doesn’t use the word cuck, nor have I thought of myself as one. But I've become supportive and understanding of her bedding with other men.Does each partner know about the other, sex and all, or are you quiet about it?
Poly means everyone knows about each other, knows what kind of relationships they are, including sexual, and consents to being in that type of relationship.
If you are having two relationships, and they don't know and consent, then you are cheating, not poly, and are an asshole.
