You're welcome

Well imo the hormones have some effect.
This is only in transgender people... there are differences in brains of women and men. There are studies showing that before birth, parts of transgender brains develop along a path the transgender person identifies with... so a mismatch of brain and body is possible.
Imo this explanation is also socially more acceptable... and its nobodys fault, neither the parents upbringing or whatever.
Hormones can change some perceptions then... some mtf people report a heightened sense of smell for example.
Additionally people get more comfortable within themselves. Like accepting their male and female parts... not having to fight them any more, externally or internally... and easing into who they are.
Quite a few people report a change on the kinsey scale, one or two points towards heterosexuality... the kinsey scale goes from 0 heterosexual to 6 exclusively homosexual.
But its not all people, some remain unchanged.
Its advised to just see what comes along... its accepting yourself... nothing to be afraid of...
And, as said, very roughly one third of trans women identify as lesbian, one third as straight and one third as bi etc.
Well its a turn on for many transgender people to imagine them active in their perceived gender, I'd say...
Questions to ask could be
would you like a bit more female body to be a bit more happy?
And you don't have to identify as female all of the time.
How would you like to be perceived ?
You might start with easy reversible steps, like changes to hair and clothing style...
and see how it makes you feel... I'd say go with a feeling of joy....
and a good gender therapist could help you along...
