Is it normal to see your balls breathe?

They react to heat, specifically the skin will loosen or tighten to maintain an optimum temperature for your sperm, hence why in cold temperatures they tend to tighten and during hot temperatures loosen.

It's normal to see this fluctuation, which you described as 'breathing', although the idea of balls actually breathing is pretty creepy.

Mine do it too. I always wonder what the little fellas are up to and I still don't know why they do it. Between that, and being able to move my penis without touching it, I could put on a real show!

They usually move up and down a bit.

Aha, dappled: my boyfriend, too, has crazy control over the movement of his penis. It baffles me (and he's said he doesn't even know how he does it, he just thinks it and it happens-- wacky!).

Shrinkage

Happened to me once. They kind of squirm in there a little

Uhm, yeah, they all do that, especially after masturbation. I think?

my boyfriends did that, i was pretty freaked, but i didn't say anything. soooo, guessing it's normal?

Ahaha. dappled, you are truly brilliant.

My balls smell
