More Options needed.
Just to be pedantic:
Even if the poll is only directed at purely heterosexual "primary" relationships with a distinction as to biological sex (which, as others have pointed out, excludes a large portion of the relationships discussed here) the poll is still missing several answers.
Male, I DO NOT want to explore, and she's free to pursue other men.
Female, I DO NOT want to explore, and he's free to pursue other women.
(As well as the neither party "exploring" options...)
Me: poly bi female, in an "open-but-not-looking" Vee-plus with -
MrS: hetero polyflexible male, live-in husband (22+ yrs)
Dude: hetero poly male, live-in boyfriend (3+ yrs) and MrS's best friend
Lotus: poly bi married female, "it's complicated" relationships with Dude/JaneQ/MrS (1+ years)
+ "others" = FBs, FWBs, lover-friends, platonic G/BFs, boytoys, etc.
