I'm right there with you KatTails - I love Boobs!!! I had never heard the term heteroflexible until reading this thread, but I guess that would fit me better than bi, since I am equally sexually attracted to men and women, but I only seek LTR with men . . . maybe I just haven't met the right woman yet!
Married to R who is a straight mostly mono male (has been willing to swing in the past and may be willing again in the future but does not like the idea of a LTR with anyone else)
My long term boyfriend D is straight and open to poly though has never practiced it and isn't looking. Currently moving in with us.
