Different families and cultures have different views when it comes to this topic. I for one believe that we get one chance to live and love - and we need to make most of this. Being affectionate and loving by physical expression is something we cultivate in our children's life at a vert early age, it becomes a part of their life. If they are not exposed to affection, they get uncomfortable when someone expresses it.
For example, the simple act of hugging. It is a very powerful and intense way of showing someone you care - I'm talking about a deep, true hug from the heart. Certain cultures frowns upon physical expression of love and their life goes on without this beautiful feeling of a hug. A lot of people who experience a real hug for the first time, burst into tears - as it break all barriers and lets your guard down.
Teaching children to be loving to one another by expressing it, is very important in building relationships.
