Measuring head

I realized recently that even though the head of my penis looks around as as wide as the rest of my shaft, the measurement of it changes drastically depending on wear on the head I’m measuring. It also seems to be much smaller than my shaft measurements when I measure, even though it looks pretty similar in width to the rest of my penis.

Anyone else notice this with theirs?

Do people really measure the head or not due to it’s inherent variation?

I only measure the girth of my head. It is 15cm while I am midshaft 17cm so there is a difference. I keep it because this way blowjobs are still possible.

How does one measure head anyways? Is it all away around the ridge? In that case, one would have o tilt their measuring device so it would loop up while tracing the ridge on the underside.

Use a tailor’s fabric tape measure. They even sell them in supermarkets.

You can measure any way you like. Tip at the meatus to corona, going down to the shaft; across to get the width; around the corona for the circumference.
