As one who enjoyed sexual liaisons with both men and women prior
to transition, I can say my sexual orientation has not changed. Before
transition, my "romantic" inclination, aside from a few men who I fell in love
with (unbeknown to them), involved women and I viewed my relations with men
as purely sexual in nature. After transition, I started to entertain the idea of
developing a romantic relationship with a man. Four years into transition and one
year into HRT, I would be as comfortable with having a romantic relationship with
a man, as I would with a woman. I believe the "change" is due to the relaxation
of my own inhibitions, as I have come to terms with who and what I am and
has nothing to do with, any kind "chemical reaction", resulting from HRT.
