For me, I enjoy seeing long gorgeous hair, but not usually much longer than butt-length or so (with a few exceptions) I enjoy long hair both in still and swinging, swaying, etc., but I especially love seeing long hair getting wet. Not just all wet, but the process of getting it all wet, the anticipation of it getting all wet. Dunking in a tub, slow submerging in a pool, shower, etc, and even shampooing, really gives me a charge.
By the way, great hair!
