I think it all depends on what someone defines as "long".

My wife had long(above waist) hair when I met her. Through the time she went short(shoulder) twice. Since she knows about my fetish she wont go back that short and will grow it to her waist. (Its mid back right now, which is also perfectly fine for me).

But shed never go above waist length for simply one reason: Its highly impractical and a lot more work than usual long hair.

And I think most women would feel like that as waist length is already a lot of work and we should appreciate that.

Pics of models with longer hair may be fine but we sould remember those women are rare and may do that for a living and dont have a normal 9-5 job.

I think its important to have a realistic view on that.
