I'm 5'8'' and I usually wear at least a little heel.  Guys have way more issues with it than I do!  I've dated guys my height, shorter and taller.  I like all types of men. 
 
If it is a problem for a guy that I'm with, I wear flat shoes. But I don't think a guy should expect me to buy all new shoes for him.  I just don't wear the 2+ inch heels!
