Many years ago I dated a girl as you describe. And her hair was magical and nearly knee length. However she was true to her beliefs and would not have sex before marriage, or even give me a hair job - this was not high school stuff, we were both in our mid 20s. So pretty much after every date I would go home and masturbate dreaming of it. At that point in life I was not interested in getting married and we went our separate ways.

Two years later we had a chance encounter...she had cut her hair super short and gone off in a totally different way of living. It was probably good that it didn't work out.
