foreskin brain

The foreskin creates electrochemical signals that are communicated to much of the body, including the brain. Information about sensitivity, arousal, compassion and the importance of physical touch. Circumcised, they are all nonexistent or at least minimal.
There exists similar information at a website search for “penis brain” by wordpress.com but, I’m afraid it neglects to mention the equally important and powerful part that a healthy foreskin play’s in sexual and mental health.

The foreskin brain is key to sexual intercourse being a fully humane experience and not just an organismic relief.
