Patent ID: 8900119

Claim:
A male enhancement device comprising a tubular shaped body with an open end and a closed endwall, said body having an inner sidewall with a centerline axis and an outer sidewall with a centerline axis, said axes of the inner and outer sidewalls parallel but offset such that a wall thickness between the inner and outer sidewalls is variable around the circumference of the body to provide a thinned portion for placement by a user over his penile frenum, said inner sidewall having laterally or diagonally spaced protuberances along a length of the inner sidewall, said closed endwall having an air passage with means to selectively block the passage of air whereby during sexual activity with air passage closed, on an inward thrust of a penis, tubular body shortens and on an outward pull the tubular body lengthens as the protuberances slide along the user's penile shaft.
