Intuition - "quick and ready insight; the power of knowing things without conscious reasoning."
Iunno, I think that's covered by "social cueues and tendencies". Your intuition is still fueled by the things you perceive and isn't magic, or necessarily accurate.
I don't see how those two are related at all and honestly treating them as interchangeable is... cringe.
There is no harm in suggesting you thought someone was gay or straight, especially because sexuality has nothing to do with outward appearance and can be kinda nebulous to infer at all. If you're not comfortable with the idea of being lgbt+, how are you an ally? Nothing differentiates a gay man from a straight one, outside of attraction to other men.
Whereas so much of trans struggles and validity relate to how they're/we're perceived. Do I pass enough to shit in the restroom that conforms to my identity?
