1. She can’t keep her eyes off of you.
If you see that she is making eye contact with you and that eye contact seems to linger a little bit too long, then you can usually take that as being a very good sign that she might feel se’xually attracted to you. The more flirtatious that eye contact is, the better. You don’t want to think that EVERY woman who makes any eye contact with you wants you like that, but you can assume that if you are getting serious stares from a woman that seem to be very flirty, that she probably does feel sexually attracted to you.
