Who knows? I am certain that the B applies to some people. Not to mention some people may be in a relationship with a T.
The Ts just have plastic surgery, no sex change and overwhelmingly they partner with homosexuals even though homosexuals claim that they don’t like the opposite sex or the sex traits of the opposite sex.
Yeah, it doesn’t make sense to me either.
If the Bs are faithful to their marriage, then they are Hs, not Bs, Ls, Gs, or Ts.
If they continue to engage in H sex some of the time, then their marriage is “open” or a sham.
And if the former Bs are now Hs, it diminishes their number in the GBLT agenda. A dalliance with experimentation (or seduction/abuse). Funny how all of the Questioning yutes are assumed to be gay but when a bisexual person claims their experiments with same sex encounters are over (former gay) they are called liars and closeted.
