my wife and i both loved it. we have had devices in the past and found them to large for my small penis. the smallest size fit was perfect and the tight bound feeling was intense. the first time she left it on for 2 days. her male freind was relieved to see me in the device and loved taughting me as he enjoyed ravishing my wife. he spent the night and the next night i finally got it removed by her after cleaning her up....awesome feeling..we now use it for 2-3 days. dave
