But that's not really hard seen as I'm about 5'3/5'4.
The shortest guy I've ever really been with was my height when I had heels on - and yeah - that was fine.
My friend used to date a guy who was her height, so it meant when she had heels on, he was smaller than her - but she liked to wear them when we went out to feel dressed up. And it wasn't like she was super tall or anything either; he was just shot. It was neither of their preference - but yeah, they liked each other - so it wasn't that much of an issue for them.
I'm 6"2' and I prefer a guy to be the same height or taller, but then again what you want and what's got there can vary.
It also depends if you like a guy smaller than you than the height shouldn't matter, it's the personality :) however that feeling that men should be taller, stronger to protect women and make then safe... Blah blah blah... The feeling that society and the media has put over us today..
sorry I babble lots when it comes to height and such... I'm just trying to give different angles and ideas.. Sorry. I hope this helps :) x
