Whilst I was in the shower checking that my genitalia was looking tip top (as you do), I noticed a great big scar running from my arse crack to my scrotum. It looks like something bad happened, but I'm amazed I don't know why it's there. It's easily my coolest scar, but only the select few people will get to see it...unless I take a picture of it and put it on Facebook.

Has anyone noticed anything unusual about their body recently?
