Guys, I see there's some talk about how big is who and I am sure there's a lot of bull in between 
Well, mine is an honest 18 cm and from what I've read up on (and heard) that it is bigger than the average.
I have allways thought that adding 1 or 2 cm's would be perfect and have looked a bit around but I don't want to waste my time on something that is going to need hours and hours per day or something that is going to be temporary.
Is there anything that you okes have tried successfully ?
