While I wish I wasn’t in the position to need this product, I am thankful for it and can comfortably recommend the “Dr. Love Perfect Marital Aid Penis Extension” for men who have had prostate cancer and difficulty maintaining an erection post-surgery. My wife would wholeheartedly agree! The product comes in varied sizes and this particular product serves well as a first step prior to “expanding” to the larger 7″ and 8″ sizes that are also available. This extension greatly helped to remove the anxiety of not attaining an erection, knowing that I could still be an active participant in providing my wife pleasure.
