You are not up on your modern lexicon.
A male bodied T would be someone with a male body, but a female gender identity, i.e. a transwoman. According to the modern notions, then that person is really and truly a woman, despite having a penis. So, if that person is attracted to men, then that makes the male-bodied T a heterosexual woman, and therefore certainly not G, nor even L. If "she" is also attracted to women, she could be a B, but that would be true regardless of T status.
There will be a quiz on this, possibly in the HR office, or at a hate speech trial if you live in Britain.
