I'm 6-2 and I agree with Asterix, being tall has never been like being handed the keys to the executive washroom of pussy.
Sure, I'd rather be tall than short, and sure I've had girlfriends in the past tell me that they are glad I'm tall, etc. however, chicks don't come up to me and say, "you're tall, I love tall guys - now fuck me" It doesn't work like that. I have to fight like every other guy, I guess I have one less thing to overcome however. (And btw, I LOVE tall women. Taller the better. I've had 2 GFs in the past who were 6 footers and tall women catch my attention. No guy will turn his nose up at any woman if she's attractive regardless of the fact that she's 5'-0". But if given the choice (not that that ever happens)
As to the clothing issue, I agree. Even at 6-2, it's hard to find clothes that fit. An XL shirt may fit (key word "may") when you try it on, but wash it ONCE and it won't fit anymore. I really don't think I'm an XXL, there are LOTS of guys a lot bigger than me, but I have to buy XXL to fit in the neck and sleeves. Sleeves being the worst. You get tired of rolling your sleeves up all the time. I personally think that mens clothing is getting smaller since they started producing it in China or Vietnam where surely I would be a gorilla. I go to Harry Rosen even and want a white shirt. I look for an 18 - 36 and it just fits me. They don't have anything any larger.
What does a guy 6-5 do, I dunno.
