Erect size differs alot everytime.

Hi guys

My erect size changes from day to day. I don’t know why.

I go as small as 6.3” (16 cm) to as big as 7”(18cm) in length.
Don’t know about girth..

Do you guys have this too?
Is it because fatigue/tiredness, because lately I haven’t been sleeping well. It’s 5 am at the moment I’m typing this lol.

This is normal.

Try warming it up a bit more. If you go from cold, right into an erection and measure it, it might tend to the smaller size than if you keep it erect for a minute or two as it warms up.

Getting the right amount of sleep really does make a difference.. And how often you masturbate.
