We know most smaller cucks usually have a predisposition to cumming faster than their bulls. Some of this may related to the sperm theory. But I wonder if it may also be related to our physical makeup. Almost all penises has about the same amount of nerve endings no matter the size, about 4000. I wonder if size plays a role here. If we all have the same amount of nerve endings, small guys may have their nerve endings closer together leading to much more sensitivity in their cocks which may mean a faster cum. Whereas larger guys may have those 4000 nerve endings spread out more, hence less sensitivity. It may be a possibility. What do you think?
