RL Gender doesn't matter. I don't know the gender of half the people I game and roleplay with and I'm pretty sure they don't know mine. Unless they've been in voice chat with me, of course. My voice tends to give it away quickly.
Romantic RP with someone who is of the same physical gender as myself IRL would not and does not bother me either. As others have stated it's the character that matters. The IC/OOC boundary isn't something that should be crossed IMO. That said, I'm still good friends with the guys I've roleplayed relationships with in the past and have never allowed RP to cause drama and conflict OOC.
