Is it always long is better?
I LOVE long hair. But for me it is more the shape, the volume, the ends.
For example this video (spoiler alert, there is some hair cutting, but the end result, for me anyway, is amazing), I think the after is so much more sexy and attractive.
If she were my wife/gf, and I saw her in the morning looking like the early seconds of the video, and then she went to the hairdresser and has this done, when she returned home, I would be SO aroused to see her like this, I would take her then and there. And then again. And again.
