Again, I never assumed that because somebody is interested in a woman they just want her body. To the contrary, I have no reason to believe it, and I assume we're discussion honest interest here.

Anyone who's not asking them an investment, which I guess still leaves plenty of options. It's a conflict of interest issue: the entrepreneur will likely consider the possible consequences on the investment outcome of their response. I would really avoid asking someone out for a data when I'm in a position of power in their regard, as I'd prefer that whoever I'm asking out is free to decide without fear of consequences.
I'm not saying that nobody can ask someone out from a position of power: I'm saying that it requires a lot of extra care, as I guess it would only be ok after you get to know each other really well and there have been multiple blatant signs of interest from the other party.
