Also doesn't help that a lot of buildings and public transport don't seem to be designed for someone much over 6ft3! I sometimes struggle to move around on planes even at 6ft2.
statistically you're taller than like 97% of guys
nothing much you can do it about it. Yes it will put some guys off ....but you'll still find it easier to find a bf than a guy who is unusually short ..so count yourself not as unlucky as you could be...
You can't change your height so why worry about it? If someone doesn't want to date you because you are "too tall" then fu*k them.
