For some, the fantasy of being a real woman or more accurately, " I wonder what it would feel like" with a man, even if that only includes walking in public with your arm on his portraying a genetic woman, does not make the person gay, bi or whatever, nor does it confuse them about themselves. . It is simply a part of the "I wonder what if" part of being gender enhanced. It is part of the question they are asking themselves about who they really are. They are reaching to the outer limits to see just how far, or conversely, how close they can come in their fantasy, to being a real woman and attempting to discover just how a real woman feels being with a man. In reality, if a genetic man ever approached them, they would be turned off totally, unless they truly are bi, gay, etc.
