I totally agree with you.

Calf length, ankle length, floor length is what turns me on most.

I don´t mind if the ends get a little thinner or if they don´t make a straight or otherwise geometric line.

It´s rather the other way round for me: with uneven ends I get the feeling that the lady hasn´t had a trim for quite some time, and somehow that is an additional thrill for me. Don´t ask me why. Perhaps it´s because I generally like naturalness and carelessness much more than perfectly cared-for beauty.

On the other hand, when i see perfectly trimmed straight ends at knee length, I conclude that the lady might want to grow her hair even longer, and what a turn-on that is for me!
