So I always thought that everyone measured girth by wrapping a tape measure around the very bottom of the shaft or the thickest part. But I just read on a site that you are supposed to measure in the middle of the shaft. Has anyone else heard this? When the ladies here are talking about the girth that they like, are you going by the thickest part or the middle? Just wondering because for me it makes a big difference. Im 5¾ around the very bottom but just barely 5" around the mid shaft.
