The Promescent delay spray has change the lives of me and my wife! Now that my ejaculations are delayed, I feel have fuller, harder erections that my blows my wife's mind (literally). I figured out the best number of sprays that work for me is about 8, and found that if I spray 1/2 of it on and wait for about 15 minutes, and then spry the remaining on and wait for another 15 minutes I get an average 1.5 to 2 hours of moderate numbness to suppress my ejaculations but yet I still have some feeling that I can enjoy it. I recently signed up for the auto subscription, so I don't have to worry about running out. Thanks Promescent!
