Gawd, this thread is really turning me on... being 5' 11, I just love guys that are 6'2 and over. I've got a str8 co-worker who is 6'4, butch, gay friendly and rumoured to be hung by many women he's slept with... also he's got an impressive package too. I see him daily, and have to try very hard to not stare at his lunch... I'm so envious of his partner.
Anyway, the very few tall guys I've had have always remain fresh in my memories.
