to women about to hit the wall saying they find you "attractive", cause you are successful ( = and not the nerd foreign loser you used to be) ?

I know the attention i am getting is mostly (emphasis on mostly) fake. I can get some sex, but I am not interested in some sex. I want great sex. So how do I respond to this gracefully?

Speaking about emphasis - I know / feel with my sixth sense that the attention givers are very likely to be ex whores trying to be prudent - I don't have the time to give it a try.

How do I find out, in the quickest way possible, how prudent she is going to be with me without investing too much of money and energy?
