Remember you are not your feelings. The way to join in union with more then one person is to form a triad of couples (3 pairs). Each couple can be sexually involved with their partner but do not have to be, but not with the other couples. That union pf the couples into a triad is on a soul or spiritual level. When people can see past personality and into the soul that's when great molecular union will occur in the human race and we will make a new leap forward in evolution IMO.
