How do you win a guy's heart?

How do you win a guy's heart? What do they really want in girls (mentally)?

You can't do anything to win a guy's heart. The only thing you can do is be yourself, and then a guy may fall for the person that you are. Just be you, that's the secret.

Thats a tough Q's, I've tried being my self but I did not win, had sex with him, bouhgt him things and loved him. Gues what I received in return, someone cheating and not using condoms and telling me that if I can not tolerate his behaviour I must just F**** off, SO I beleive guys dont really know what they want because, all girls have the same 'thing' whether young or old.

I beleive it is time guys start behaving like human being and not dogs

I think you need to really care about him. He can tell when you do. Don't argue with him. Let him feel in control. Be playful and friendly at first. Thank him for helping you with whatever. That's what I think.
