There are many theories on why people have trouble showing affection, and also cultural studies on how different groups show affection. Some theories suggest that such gestures of affection are often determined by our degree of nurturance as children.. In families or cultures where affection is common, people will more commonly show affection. Others also suggest a gender difference, especially in many Western cultures, between showing affection to boys and girls. Girls may receive more affection than boys, especially when they are emotionally distressed. Boys, alternately, may be told when they seek affection, such as when they are injured, to toughen up. Even though we think we’ve shed these gender differences, evidence to the contrary is available in a variety of studies; we are still harder on boys. This can matter a lot when boys and girls grow up, because girls will expect a higher degree of affection than boys, who have been nurtured to give less. Women will claim their husbands have trouble showing affection, and men may actually complain that their wives show too much. There are other reasons why people may have difficulty showing affection. People who have experienced sexual or physical abuse may find it very difficult to receive or give affection, even very simple things like a caress or hug. For these folks, touching itself has become a violation of self, and they don’t want to receive touching, or give it and possibly be considered as abusers too. More simply, some children are just less acclimatized to affection than others. Parents can love their children but have trouble showing affection to each other or to children. http://www.wisegeek.org/why-do-some-people-have-trouble-showing-affection.htm
Do not be afraid of showing your affection.
Be warm and tender, thoughtful and affectionate.
Men are more helped by sympathy, than by service;
love is more than money, and a kind word
will give more pleasure than a present.
