Wife is 5'6, which is fine for me.. shes a bit tall compared to girls in china, but about normal in england.
last 'serrious' girlfriend before was around 5'9.. that was ok.
Before that though, I dated both ends of the spectrum, had a girlfriend who was 4'11, Horrible.. got dirtly looks everywhere as If I was a child snatcher. When I was a teenager dated a girl who was the same height as me, 6', didnt like that either.. felt wierd.
So yeah, anywhere from about 5'2, to 5'11 and its cool for me
Looks wise
