I would say that, if the only experiences you've had involving multiple partners have been purely sexual and without emotions, then those were not polyamory. Polyamory is not about just fucking around. Sex-only liaisons would simply be considered non-monogamy, even if everyone was truthful about what was going on. Polyamory is about cultivating and maintaining multiple, mutually respectful, consensual loving relationships.
So, as far as asking us "what to do next," have you figured out what you want? What is your current situation and how do you envision creating what you want for your life?
