Cock longer when 70 erect than 100, why

My cock is meassurably about 1/2 inch longer when it is only 75% erect than when it is fully erect.

As length is my problem, I find this depressing.

To explain:
I have a slight upward curve (like a banana shape allthougt much less extreme), and an upwards erection angle when it is fully erect.

This is very ironic, I tend to meassure my cock at 75% erection (when it is straight out instead of upwards) because that gives me a 1/2 inch extra.

What does this mean? Why? Can I use this in any way to gain easy lenght?

I would gladly appreciate some small inputs or thoughts from educated PEers.

First, I think you should measure yourself when you’re fully erect. There’s no point in using a trick to increase your stats; you’re only fooling yourself.

Second, my girth is larger when I’m about 60-70% erect than it is when I’m fully erect. So you’re not alone in that way. It happens to lots of guys. It’s nothing to worry about.

As for using it to your advantage, I don’t know about that, but maybe someone else has an idea.

Using it to your advantage?

I’m going to put my neck on the line and say there is NO WAY to use this to your advantage.
