Like others have previously said (but it's still a bit weird for me to say it): I also got my bigger cock from my mum! (Sorry, dad). As a kid, I saw dad 'soft' often; he didn't bother kicking me out of the room when getting dressed. So I know he'd be 'average' when hard. Mine's already twice bigger than his, even when I'm just soft. My mum's half black, so I know where it's coming from, in all probability.
