Do guys like a little change?

I do, I don't like hair that is mostly over the shoulder, it looks like a flat heavy curtain.

As a bonus, a little shorter hair, say just above the shoulders, cut in layers, flows in the wind, and is super intoxicating - I recommend you shorten it up just a bit - especially if your planning on being seen walking around outside during the spring and summer.

I prefer long hair on a woman, exactly as you have described. It's more feminine.
While they may have "long hair" men don't generally view hair the same way you do.
For men, hair normally falls into quanta more than specifics.
Long, really long, short, really short.
Having layers will set you apart already.
I tend to dislike constantly changing hair styles, you are who you are. Not who your hair tells people you are.

Definitely. Ever changing hairstyles is part of the fun of a woman and having a different style will help set you apart.
