I am tall (5'9") and I have NEVER had a problem with guys.
I love being my height. My boyfriend is right around 6' and we match up perfect in every aspect.
The only pain in the ass is finding clothes that fit like I want them to. Seems like most things are made for shorter women. It is funny to me that men have a "big and tall" store but all women are expected to be 5'6" and shorter.
