I don't think mine's got any more noticeable as I've got older. It seems more obvious when I'm hard because there's a brownish mark and the skin on either side is quite different in colour, but I tend to get compliments and no one's ever complained. I didn't notice it when I was a kid but as soon as I found out what circumcision was I started to notice the scar on my own and on my mates, so for me it was just a matter of me becoming aware of it rather than it getting more obvious.

I've discovered that a lot of cut guys don't even realise they've got a scar.
