Mine did
Before hormones, I was straight (only into women).. The thought of being with a guy kinda grossed me out.
Somewhere along the line during my transition, the idea of been with a man did not gross me out and I started being attracted to them as well.
so post transition, well I am now bi-sexual, with more of an interest in men... so a straight woman with bi-sexual tendencies. I am currently in a long term relationship with a man (dating 13 months now), I love him to bits and I love being his girlfriend and maybe someday I would love to be his wife.
