If he chases her for 5 months does he have feelings for her or is it still just for sex. If he shows signs from body language that he is into her. He mirrors her gestures, he jumps into conversations she's having with other people. He stares and smiles, and sometimes waves hi. Does he just want sex from her? Or what?
Ok there might be a sexual attraction but it usually always starts with that anyway. its not only for sex he might know even want it if a guys is in to you its you not your pussy pardon my French lol give him a chance you'll get to know him a lot better if you and him and if he's getting to hot and fast to fast then get up and leave his ass lol
