I was nearly 6'3" (189) but I've lost 1 cm over the years. I prefer tall women. My wife is about 5'10". We fit together really well, if you know what I mean.
I had a witty, intelligent, stunning girflriend who was only 5'3" (and who I probably would have married if she hadn't dumped me!), but I won't lie: it sucked to constantly have to lean way over to kiss her, hold her, or even hear her when it was loud.
This little rhyme always comes to mind when thinking about couples of vastly different heights:
"Nose to nose your toes are in it. Toes to toes your nose is in it."
Chemistry, personality, intelligence, values and sense of humor are all more important, but all those being equal, give me the tall girl.
