How fast can a girl tell if she wants to sleep with a guy or loves a guy?

I have heard women say they could tell in five minutes if they wanted to sleep with a guy, my ex once told me she loved me before I asked her out, and I have heard some girls say they can read a man in the first few minutes by body language and stuff.

So my question is: how fast can a girl tell if she wants to sleep with a guy, loves a guy, and how much time does she need to read him in general?
