I've only dated one tall girl and saying that, she was only the same height as me perhaps a little smaller, she is gorgeous, no doubt, but it's not usually my preference. I've dated a lot of girls between 5'3'' and 4'11'', I myself am closing in on 6'0'', ironically the girl I'm most attracted to is 4'11' and I think she is gorgeous and sooo cute which is a lot to do with her height. I don't really care what others think, afterall they aren't the ones dating the person.
I think taller guys are always a good thing but really? Does it matter if your friends disagree? He's yours right? Shorter boyfriends back in my day were called "boobie" boyfriends lol, can you guess why?
I have had 2 boyfriends and both of them were close to my height, only a tiny bit taller I think so we were face to face all the time.. I liked that. I've never been with someone who towered over me, but I wouldn't have a problem with that.
