Okay, for starters, it's really helpful when you post in standard English, not slang, because then it's far simpler to understand what you're asking. If you could do that in future posts, that'd be very helpful.What goes on in your fantasy life and what goes on in your real life are two different things. And it isn't unusual for our fantasies which are more divorced from reality to be more "effective" than those which are based in reality, or around lovers whom we already know intimately.
I would add that it is HIGHLY unusual for anyone, men or women, to reach orgasm from the onset of arousal in less than a minute, and in women it is practically unheard of. I suspect you may perhaps be confusing arousal and orgasm (you can look into that here: http://www.scarleteen.com/sexuality/response.html).
Sexual orientation is something we find out about as we grow, through our *actual* attractions (to real people), with cues from our desires or fantasies, and based in who we choose to have relationships with. So, as your life goes on, what orientation you fit best in will become apparent. Really, one does just sort of "know," when the time is right.
Don't sweat it.
And in the meantime, can I suggest reading some articles which explain sexual orientation accurately in our Gaydar section?
