I've seen several, and of course, I am more attracted to her with longer hair, though I'm still attracted to her presently (it's slightly longer than her shoulders now)... meh.
I asked her once if it was ever much longer, like butt longer, and she said "no, too hard to keep them looking good. Too long."
Saddening, but all is not lost, she did say prior to that that if I ever told her about something that would make me more attracted to her, she would welcome it.
She's coming to visit me in September, and I want to bring this up, but WITHOUT making her feel inadequate for her current length. Need the perfect words to do that though. I'm still attracted to her now, absolutely. I would simply be attracted to her MORE if her hair was much, much longer.
