I believe it is very common.
I live in a big city, which is placed in a valley.
Everytime I go on vacations to my village in the mountains, the oxygen swells me up.
And not only my penis. I have tight clothes that don’t fit me well from the second day there. The same clothes I wear where I live!
I remember when I left my village a long time ago and came to live in the city, I needed new clothes from day one. My pants were fairly loose.
No, I didn’t lose weight.
I wonder if humidity also plays a part on this.
