Physical Intimacy

Talking to a friend yesterday I began to wonder how much of physical intimacy is acceptable between two friends? Zero or in negatives? Or is there any term as such between friends? I have grown with a lot of girls around me, all very good friends of mine and I have never shied away from hugging them when I was happy or holding there hands when sad or keep my head on there shoulder when really bored. But I have always believed in keeping a respectable distance and strongly advocate it………hypocrisy? And what happens when you think you are sending out the wrong signals??? As a guy I know it doesn’t matter but for a girl that can be a pretty bad situation. And if one does decide to be the decent one not indulging in such acts, is it because of the conscience hitting back with a moral sword or to escape being talked about???

P.S I need views to come to a conclusion, plz. Help!!!
