Society wants women to play games. I am incapable of this. If I'm on a date and we can't bear to end it, it's been 8 or 9 hours, or even just a few hours and no one wants to kiss goodnight and go home, if I know I would sleep with him eventually provided he can show me the paperwork I need to see, then I say, let's go for it. Why wait if we both know it's what we want. The one exception is if I feel something more complicated than a simple friendship might be building up. Then I'll wait to see what my emotions have in mind. The surest sign I'm really into someone is an outright refusal to have sex with him until he is mine.
