lolo, you're killing me. girl take her to dinner, have a glass or two of wine, go back to her place, put on some soft music, ask her to dance, pull her close, kiss her neck softly, if she responds by pressing you against her tightly, kiss her lips and let your hands roam. If she begins to moan softly, unbutton her ... well you get the picture. Now, and this is very important, if she say STOP, or NO, or I ONLY LIKE YOU AS A FRIEND or variations of the above, you'll know the answer to your questions. If she doesn't say any of the above, or run screaming from the building, you may proceed with the seduction.
Your next post should be something like; "hey guys, I'm really in love" or, I thought my best friend and wildest fantasy was bisexual and last night I found out she wasn't and now she hates me, what should I do?
From your numerous previous posts I know you're dying to get her in bed so stop playing these mind games with yourself and just do it.
