My sexual orientation has not changed and I've been on hrt for 4 years 1 month. What has changed is the mechanics, I get turned off immediately if I'm treated badly and I'm not courted properly, just like a female. HRT for me, has changed sex for me, from more of a physical pleasure, to an emotional and sensual experience, if I connect. I still put up a strong male façade though, due to my work/home environment, exhausting, and even makes me covertly cry, at times.
