For me I love to have a lady with such hair, she would be my partner than.
I had a girlfriend once and she had shoulderlength hair. She was very happy to have her individual hair softly pulled (of course it was a little strand of hair because it is a difficult thing to do to pull one hair)
She enjoyed it that much as it would relax her. I tell you I would love to do that with her. I also massaged her scalp, that was heaven.
Unfortenately she was a difficult person so the relationship ended.
As I can have a longhaired girl as a partner again it would not have to be with one quick moment but than you can enjoy a lot more.
Yet I can understand that when you see a girl/lady on the street with very nice hair you would love to feel that.
I would do that only with her permission though.
