Depends on the culture from what I'm able to research

Yeah same here

As I understand it a "sister wife" is someone who is only physically intimate with the male in the relationship. A "bi sexual" relationship is when the all partners are physically intimate with each other. So an example of a "sister wife" scenario would be me (husband) having a sexual relationship with my wives independently. One wife never with the other. A "bi sexual" scenario would be my wives having a sexual relationship with each other and not with me present. Otherwise that would be more like a threesome. I wonder if this helps.
