Foreskin and Foreplay
The foreskin is not only more densely populated with receptors than the rest of the penis but has a greater variety of them. This allows us to think that sexual sensation of the foreskin is not only stronger but has a different quality from the rest of the penis. We have no strict objective scientific proof of that. Plenty of evidence, however, comes from the very owners of foreskins. Doctors, biologists and other scientists are among them, and many of their testimonies are documented. They assert that sensitivity of the foreskin is not just stronger but is also quite different from that of the penis glans. If you are one of them you can confirm or deny that.
