Everything feel good? Excellent! Play a bit if you want. Did something seem odd, not quite right? A lump, or hardness (no! not in your dick!), does one seem enlarged and tender? Make that call to your doctor for an appointment to have him give your Boys a thorough once-over. Never done a ball check?
A kindly doctor demonstrates on a real live dude, and then he does some nut exploration of his own.
Now, your job is to email, text, Instant Message, Tweet, FaceBook, Direct Message, post to bulletin boards and forums, urging every man you know - and even those you don't - to do that Ball Check. This is why it's called Buddy Ball Check Day.
Sure, you can get together with a bro and check each others balls; that's perfectly acceptable - as long as the work gets done before playtime begins.
