Typically, I don't find long hair on men attractive. Especially men with long hair who seem like they never wash or brush their hair.
There are exceptions, of course.
Fabio isn't one of them.
My husband prefers shorter hair on women. Thus, I occasionally cut my hair pretty short. But I personally like my hair longer. Partly because I'm too lazy to cut it very often & my hair grows really fast. Longest it's been is to the top of my butt...shortest is top of the neck w/feathered sides.
