If it's not luck, what is it? Studying hard in school?

I don't consider myself especially big, but others seem to. So I suppose I take it for granted - it's the only penis I've ever owned. And it has created more problems than it has solved, so I'm not sure I'm as glad about it as others seem to be about their penises.

In a way, I'm kind of curious about what it would like to be somewhat smaller than average in size.
