When did you have your first poly relationship?

Ummm technically a couple of years ago, though I was never allowed to see anyone else, it was always a problem. But he had a girlfriend and was always pursuing girls. I’ve always just had “friends with benefits” sorta stuff before that because it worked out better.. I guess I just moulded the relationships to what I needed without it having a title or anything ^-^ Now my idea of poly is different too, I don’t want multiple partners to sleep with, I just want to be able to show people my care and affection for them >.
