My gender identity has never affected my attraction to other real, present people. Always, "in the field" so to speak, I'm pansexual and if I like a person, I like them and neither person's gender has anything to do with it. But if I think about a relationship of any kind, it's pretty much always with a person of my own gender regardless of what it is at the time (so, like fantasy-omnigay).
The romance part is more complex. My romance tolerance starts pretty low. I have pretty much always considered it kind of a waste of time and effort, and as a "girl" I more or less just find it tedious and pointless. But in "guy mode" or even sort of in the middle, it makes me really uncomfortable. To the point that (I think I said in my intro) my ex used to ask me if I was "allergic to kindness" because he would offer to carry my books to my locker, or he would give me candy, or whatever, and I didn't want to accept it. For a long time because of it I had a lot of reservations about IDing as aro because I felt that it "wasn't valid aromantcism" because it was so heavily influenced by social gender roles and dysphoria. But obviously I got older and wiser and now here I am.
