Yet these same adults know their children truly love them and other people important in their lives. Feeling love, falling in love, sharing love doesn't happen on a timetable. You haven't even verbally expressed your feelings to each other. You don't know each other yet on a deep level. You don't yet know her plans, her desires, her moods, her hopes, her dreams.
Intimacy takes time.
It is not as simple as taking apart an engine. Sex without intimacy is a cheat. It is like being given the answers to a test without having the understanding behind the answers. You can't hurry what is right. Love will not disappear.
