Uncircumcised: How long before you wash?

This is something I've noticed from discussions with some of my friends who are likewise uncirced: Some can go a couple of days without washing before you start getting 'the scent' whilst others it takes only a few hours.

For me, I have a shower in the afternoon and by evening I'm getting it - but then again it doesn't get real bad though, you know? Probably depends on the weather too...

How long for you guys?
