Natalie and TeddyBear do have it hard, and I empathize.
I too have a physical type, though it's a lot broader than either of yours. And women outside it don't really do much for me either.
But they also have to be smart, and cheerful, and bratty, and submissive.
None of this is all that hard. But when you narrow it down to those willing to be with a Poly, married man, the pickings get very slim indeed.
It may be a long long time before I stick anyone's name in my signature. You're all very lucky.
P.S. Natalie -- I'm 6'3 as well. Maybe if I wore shoes... :-P
