Our first "real" encourage terms with poly was with friends of ours. We have known them for a long time, and always knew she was bi. Originally we thought they only just played with other females but found out in discussion that they were in fact looking for a full time gf for a poly relationship. The other half being bi this last one led to discussions between us about it, as well as research about poly and the lifestyle/community. Low and behold, we found our way here to this amazing community.
While our journey is still pretty young. We have been having a great time so far.
