I 100% agree that it is not "forced" because that would imply rape and having zero choice, which we all reject. A better term would be Coerced-Bi however we can nit-pick any term (and sometimes we do). Many Dommes will say "Don't call me mistress because I am not your side-piece helping you cheat on your wife"... Yet we still use that term because the general community recognizes and embraces it just like "Forced-bi". Hell, BDSM itself is a terrible term for what we do if you break it down.
