So do you mean that you are unable to remain monogamous or that the people you date are often non-monogamous? I am consdiering this myself because I am tired of the breakups from serial monogamy. Like, I just am coming to accept that nobody wants me for a serious long term relationship. Maybe if I wasn't monogamous it wouldn't be so heartbreaking when a relationship ends.
RE: Are you poly or otherwise ethically non-monogamous? If so, how did you discover you preferred these types of relationships?
