This is because you’ve spent your whole life involuntarily clenching this muscle. Your anal sphincter, the muscular ring at the base of your colon, feels very tight when you first start to play in it. There is a third pleasure spot: Your hole. It’s roughly the size of a walnut, and it feels really good when pressed or rubbed (by prostate toys, fingers, etc.). The prostate is a g-spot, and it’s located about two inches (depending on your age and your anatomy) inside your ass.
Most guys know the underside of the penis feels good when stimulated.
