i haven't been in a relationship yet, and i'm open to the idea of having 2 or 3 girlfriends, but i wouldn't mind having just one. would the correct term for people like me be "open to polyamory", or just plain polyamorous?
Whatever term helps you self-identify in a way that's healthy and gives you the tools and language to find the relationships that work for you. Some people use terms like "polyflexible" or "mono-poly" to describe themselves as someone able to have healthy, fulfilling relationships that are polyamorous or monogamous.
