Let's try to feel
Imagine a girl who you really like. Some very very reputable man leads her by the hand and says to you "It's yours!".
You don't have this girl zavoevyval. You can only APPRECIATE this gift and enjoy it. You will not only enjoy her body and cares about her health, you buy her clothes make it look nice, you could drive her to the cafe and be this enjoy because you do it for someone who belongs to you, it's like as if you're doing it for yourself.
Compare this with the usual situation:
You meet a girl you really like, you give her flowers, you take her in the cafe. But if you think about it you do not in order to please her, and in order to achieve from it reciprocity, love, etc.
In fact, you're doing it to her that you can get, and to itself you don't care. If it turns out you're going to sleep with her and boast to friends.
If the girl is smarter, she will tame you so you start to chase her and think it love. But this is just a selfish feeling, she is a tease but leaves empty. And in this case to itself you don't care.
Only if you feel that the girl belongs to you, you meet is not easy , and it's yours, only in this case, you care about her well-being, only in this case, you give her flowers and lead in the cafe because I want that she enjoyed it.
