I buy my mega sized elephant condoms at Amazon and they are a perfect fit for my 18cm.
I prefer XL-sized Trojan condoms from the U.S., though, because they give me a little more girth space and have a lot more lube on them.
To all of you sensitive guys on this board, is this the proper time for me to mention my size?
With all the bashing going on lately, I figured you were taking the South Park penis size mesurements to heart.
