Trying to understand the intentions of a woman can be as hard as rocket science sometimes.
A woman might really want to be with you but hardly utters it directly to your ears.
Here is how to tell if a woman is trying to seduce you according to women themselves;
1. She shows you some skin
This doesn't mean she will life up her dress or something but it's possible too. The main point however, is that she will expose to you some parts of the skin that you wouldn't expect her to. She can let you catch a view of her clavicle and make no move to correct it or take some postures likely to attract your eyes and again make no efforts to sit up.
Women are seductive in many ways and they actually know how to override a man's self control. Because she knows you might not have all the courage to spark up things, she starts to touch herself in ways likely to affect your biological reactions. She could either begin playing with her air or touching places like her clavicle just to let you know what she wants you without having to say it.
3. She is generally open to you about intimacy issues
No woman interested in anything else other than pure friendship would feel free to talk about anything deeper about intimacy with you. Late night talks about things that excite them sexually would in a way mean they don't mind getting really intimate with you. It's upon you to make a move.
