I think Matt's is 7.45" so he cannot be of much help here...
I wish, but then - my friend has 7.75", and his most recent girlfriend could barely fit it to start. Things worked out [until they broke up], but I think it's safe to say the universal ideal size is probably 7", until they get too big.
I'd take a CM on my dick, but not much more. I don't think women think much more is better, although some do.
