My wife wanted to have a complete body massage for quite some time but had not seriously followed it up. Recently the son of our close friend of ours visted us, while talking he mentioned about massages and told that he used to do masaage.My wife told him that she too wanted to have one and after the discussion, he had offered to do her.In the evening when I was back home, she told me that the guy had given her a complete body massage to her satisfaction and she felt it was ok for her and had asked him to give her one once in a month. But i suggested her that she should get massages only from a professionally trained one and not from a self trained one but my wife says that the guy did good work and hence she wanted to have it with him reularly. Just wanted to know that massage from a guy not professionally trained could lead to harmfull effects?
