I know that's a bit strange...

Anyway I've never seen my dad naked but he has a lot of brothers, who I suspect are quite well hung, they're 'big' guys, not all that attractive, but they have attractive partners. Also my dad is a bit of a ladies man.

I don't know how big he is but just quite big I guess. It is hereditary but there is still a chance that a son won't be hung even if his dad is huge. Usually though, they are.
