I'm not a fan of thinking of the 'who's the boy and who's the girl' thing in relationships. You're both girls, with different levels of femininity/masculinity, but that doesn't mean one has to fit in one role or the other. But, of course, that's just my opinion. Heh. Hope you can find someone you're comfy with! Nothing wrong with how you feel. Sometimes not having a label on it can help. You are who you are, whether gender-fluid or whether you identify with one more than the other, and you're a lovely person through it all. <3
It's probably easier if it's a bar setting, just because the expectations aren't the same of, say, asking a friend out. If one says no, there's no hard feelings. If the friend says no, might make things awkward. All depends on what you want. If it's just experimentation, someone who's into that too (maybe in your entourage?) could help, or else someone at a bar would be good. But for something more long-term, of course, bars should be avoided... cx Not that it's /impossible/ to meet someone at a bar (my cousin met her husband at a club, haha!) but it's, you know. Not the same vibe.
Good luck! Some girls like shy girls. <3 It'll come in time.
Calling them Monday is a good idea - just to check up.
I was never into the picking-people-up-at-bars thing, but I hope you can find one and it goes well for you! Just maybe make sure you know your limits and don't drink too much if you plan on going home with someone, just in case. <3
