Our take on the Bi, Bi-curious and Straight question is this:
If you are straight, play only with the opposite sex and have no interest in the same sex, You are STRAIGHT!
If you are Bi-curious, play with the same sex 2-3 times, decide it is not for you, you are Straight. However, if you play with the same sex 2-3 times, enjoy it for your own personal reasons and not just to please others, you are no longer curious. The curious portion of the label should be removed.
HOWEVER!!!
If you are into the opposite sex more and only enjoy the same sex as an appetizer (so to speak) then you are Bi-comfy or Bi-tolerant.
If you are equally attracted to both sexes, you are simply Bi. The best way to find out if you are truly Bi would be to have an experience with the same sex and no interaction with the opposite sex in that event. If you walk away feeling satisfied...Well, you are most assuredly Bi.
Perhaps the owners of the swingers sites could add the options for Bi-comfy or Bi-situational and even Bi-tolerant. A few other options could not hurt. It would also save on the profile size. HA HA HA! Like our profile is short! HA HA HA!
Again, this is just our .02
