I am not sure exactly how I would define romanticism but I kind of wonder if it has something to do with just dating. For instance I would rather buy a woman flowers, go on a date to like a movie, or out to dinner with a woman than a man. Strange though how I am more sexually attracted to a man than a woman. I do however recently have been getting heterosexual urges for women and have been getting off thinking about it or watching lesbian porn. Another thing that seems strange is how when I am out in public and get turned on by a guy who is shirtless or their taking off their shirt. It is almost to the point where i could or will get off without touching myself. That doesn't happen to me with women. However, I can be sitting around and think and fantasize about having sex with a woman and I will get really turned on and go to my room and get off. I know that I didn't really talk about romanticism that much and wonder if other things besides the stuff i mentioned encompass it as well.
You said "another thing that seems strange", but really, your experiences aren't strange. Lots of queer people experience the same things you are. The boundary of romantic actions/thoughts is different for everyone, but usually includes all feelings/actions that concern another person that have nothing to do with sex pr their body parts. You can feel a romantic preference towards one gender and a sexual preference towards another. That's totally normal!
The concept of romantic feeling is a little nebulous to me, too. But generally I think of romantic orientation as who you gives you butterflies in your stomach, who you can imagine yourself marrying (now that same sex marriage is legal in all 50 US states), who you can get infatuated or crushed out on. As opposed to who makes you aroused, per se.
