sounds like dear old dad tends to pass on the dick gene for most guys. i wonder if dads with big dicks are more likely to undress in front of their sons than dads with small dicks. probably. it's learned male locker room behavior.

i only caught a few glances of my dad's equipment growing up, but he's definitely hung more than me. he was born in europe so he's uncut, which completely confused me as a little kid when i saw it!
