I asked woman to come out with me lunch so that I can talk to her. I want to have sex with her. Does

My answer to your question is that the woman that you asked out to lunch most likely knows that you have an attraction for her. I would think that if someone asked me out. I don't know if she'd feel that you want to have sex with her, just by u asking her to lunch, but, it all depends on your conversation, and behavior. So, to finish my answer, it depends on what was said and done at the lunch date. Body language is a key signal.. Were you touchy-feely with her? Did you flirt? Ask urself how she responded to your questions.

i think what really clear for her is that you like her why not try to court her at least before you say you want to have sex with her
