Unless a woman has displayed threatening behaviour, there is no assumption of danger. For men, the reverse is true; unless a man has demonstrated that he is not threatening, or a woman has established a personal relationship with him and had an opportunity to develop trust, she tends to assume the worst. This means for men there is a very delicate and subtle line from appreciative to creepy.
