The word "love" may be used to describe an experience or a feeling felt by someone for someone. People think of love only in the narrowest possible sense. Physical contact between a boy and a girl is all what they think... Love is, in reality, (as I feel) something which can not be framed into words properly. Anything you say will only be a vague representation, not what love actually stands for...

A husband and a wife. No kids. They do not indulge in any sexual contact at all. People might say this is not love
