I hang 6" soft, which is a good size, but definitely not crazy big like some guys on here. I've been bigger soft than some of my friends who had hardons ranging from around 5.5" to just under 6.
I grew up with nudity being totally open and so got interested in this topic from seeing how I'm bigger soft than my father when he's erect. We've seen each other soft and hard and did compare together and telling each other our sizes (that's just how close our relationship is on such things), and his is 4.5" hard. His feelings on it switch from jealousy to proud, but never malicious times when he's been jealous. I must admit that having that advantage over him, was an ego boost, even though his is smaller than average hard and not typical to others here whose soft sizes are extremely bigger over average erect cocks.
