Early in my hobbying years I remember talking to a T-girl...this was before texting so actually had to talk on the phone. So yes, I am old.
Anyway she/he said that being curious or attracted to a T-girl does not necessarily translate into being gay or bi....as almost everyone assumes. She/he felt if you are attracted because she looks hot as a woman...then you are attracted to femine beauty, ie not gay. If the T-girl looked totally masculine, like a guy with breasts, you would likely not be attracted or curious, hence not gay,
Made sense to me.
