The foreskin was designed by nature to cover the penis head.  When the foreskin is retracted, the penis head rubs against the fabric of your pants, causing a permanent callous.  When the foreskin is properly stretched over the penis head, the callous fades away and the penis head once again achieves the sensitivity that nature designed it to have.  Our foreskin stretcher will encourage your foreskin to cover your penis head.  The foreskin stretcher is also a great solution for  those of you with uncomfortably tight foreskins.  Click here to order.
