I have had quite a few boyfriends in my short life. What I've realized is that everyone loves differently. Some people are vocal about their love, some physically express it.
There are a number of ways to express love (or intimacy):
+Through verbal communication
I wonder if the way we express ourselves in relationships have at all to do with culture, family, or even both.
From what I've observed in the Latino culture in general (from friends and family) we seem to express our love in a more physical away.
In my personal experience I found that certain cultures are far more open to expressing love than other cultures. Me personally? I am a VERY expressive person -- through words, touch, action, gesture.
