Atheist - I have been a student of human nature all my life and I have learned two things about women.
One - If you ask every woman you meet if she wants to have sex with her, and she is at all aware of anything, she will have already pegged you for the desperate numbers-playing sad excuse for a human being you so clearly are, because let's face it, if you never had one iota if respect for yourself, that means you can't have any for her.
And two -
If a woman you don't know is interested in having sex with you, she will let you know.
If she isn't letting you know, simply being insensitive enough to ask her anyway is not going to change mind.
