I agree with Doc...I don't really think there's a need for a label. You are what you are, and honestly speaking, what purpose does a label serve you? What's wrong with just being misskeena instead of gay/bi/straight/whatever? While I certainly understand that "knowing" gives a bit of security, I wouldn't stress so much if you're not firmly decided. You're you, and for now, that's all you need be.
Also, I think you may be over analyzing your gay male friend a bit. I think, as long as you didn't give him the perception you're grilling him, he wouldn't mind answering a few questions...like how he knew he was gay, if he was ever confused in his orientation...things like that. I'm not sure I'd necessarily use him as a sounding board for your specific situation, but his experiences might help you a bit.
I wish you all the best, and good luck.
Hugs,
Harley
