I like Doc's idea. But seriously, you should bloom where God has planted you. If it be His will for you to connect with a poly-group, then take that as an answer to prayer. I'm 49 and have been with my lovely bride for 25 years. Even-though I pray for Gods will to be done in my life, and though I have the blessings of my wife to seek another wife; I'm not sure what I'd do if another woman came into our lives.
First she would have to be a believer in Jesus, second (as just as important) she and Karen (my sweet-heart for 25 yrs) would have to edify each other (no competion in my house), next....................not sure. Even though my pastor (RRP) and I have discussed it, I not sure I really want to be a husband to more that one wife. Just being the man God wants me to be to this woman, at times, is enough for me.
