I have been in your shoe, but remember, even if she wants you, and I am sure she is at least curious, as a woman in todays work environment,,,,she can always get you in touble by just saying you looked at her in a certain way. She maybe curious, but she may not take the chance for black cock for another 15yrs. I know what you mean by the perfect big booty white woman, its like a fantasy in front of your eyes, but remember there are a lot more white women like that.
Here is how you handle it, first of all forget thinking something is going to happen,,,,,that constant hoping and wishing is not doing you any thing constructive. What you do let it be known how beautiful certain white actresses are, but do this with out putting down black women, because this will make your attraction seem shallow. \Shows your attraction to white women more by being friendlly and helpful with the white women around the work place, and if possible bring in a white girl friend around work. It will have the same affect as if you saw her with another brother or over heard her saying how handsome Denzel or Will Smith is. That has worked for me.
