Im a trans woman, and im bisexual. My attraction to women goes from "I wanna be you" to "I wanna be with you"

Sometimes I end up looking at the downblouse, mostly since im taller than most cis women. Recently I was with a friend, everything ok, however. I was able to see her nipples because of the blouse she was wearing and her loose bra. I was normal about it, but I was feeling bad and uncomfortable because this is my friend and I felt like I was kinda invadir her provacy somehow.

What I wanna ask is if yall notice when someone is watching the downblouse and how you feel about it.
