In my opinion, V-types are probably a chain of*open relationships
*and not really poly ones. Fine, some of you can call them networks to encompass the whole chain of people involved, but I think V-type polyamorous relationships are a misnomer...it's just part of a chain of open relationships.
Ummm.. my V relationship is just that a v. Murf is monogamous. There is no continuing chain of partner there. Butch is polycurious BUT is not seeking other partners. So the chain ends on his end. I am polyfidelous. I have no urge to be with anyone but Murf and Butch.
So you are wrong painting all relationship with one brush.
