Whenever I bend 100° or lower, weirdly, my penis seems to shrink.. when i stand up or lay down in a straight position, it goes back to normal! Is this normal?
Your penis is attached to your body behind your testicles, you can feel it when you're erect.
As you bend over, the penis is pulled back, and will appear shorter, it's perfectly normal, and it happens to everyone who has a penis.
Hope this helps.
