Sex attracts, but physical attraction alone cannot bind two people happily together for very long. Sex is very intimate at the physical level, but there may not be much personal or emotional depth involved. Love is not effortless. To the contrary, love is effortful. The fantasy of sexual freedom sells products, and it sells films, books, and movies.
Men are truly among the brainwashed.
They are not only brainwashed to assume that they can't turn down sex, but they are brainwashed to believe they have no self-control. Anyone who would reject you just because you don't take care of his or her sexual needs is making a totally self-centered statement. Each of you should look not only to your own interests, but also to the interests of others. Many girls have sex for non-sexual reasons and do whatever the boy wants because they want the boy. Mature love is when you love the person as he or she is.
