Compression of the CS.

The CS is easier to compress than the CC. But what happens with the penis when we compress the CS?
Will the total penis volume decrease as we compress the CS or will it remain constant.

My I compress my CS manual, my glans gets bigger and harder. If I compress my glans, my CS expands. If I compress both I get a wider penis. (I’m not sure if it’s the CC that expands, since it’s not connected to the glans/CS. But my penis gets wider..).

What do you guys think about the CS and it’s compression?
