Well we are on a big cock website so you have to expect some ladies have seen some very big ones.
I'm 7" x 6" and I'd say that for about 50% of women I've been with, I'm about the biggest (or joint biggest) they've had. Or so they say, they might just be saying that to be nice.
I remember one girl said her ex she'd just split up with was 11", what a way to dampen a guy's spirits!

By the way, does anyone know who's that girl on thirteenbyseven's avatar? She looks great!
