Ok this will not stop him from having his orgasm but it "should" let him keep going if what you are looking for is a longer night of fun. I personally have had this problem for years, lack of concentration or too much concentration either way does not work for me, start and stop does not work for me either, I also tried to use delay creams and gels that are supposed to desensitize me also did not work at all. What I have found is a nice herbal supliment that allows me to stay hard, I am guessing much like viagra (never used that stuff before though), although I have my orgasm. Since I have been using it I have yet to leave my wife unsatisfied with the duration of our sexual exploits. We found it while shopping in our towns only adult store and if this is something that you are willing to try it is called Vigor-25 and yes they have thier own website which is www.vigor25.com where you can read about it a bit before you try it. So if nothing else helps you I really suggest giving this a try as it has been the only thing that has worked for me. I can now pretty much go for hours and not have to worry about if I am cumming too soon and leaving my wife unsatisfied.
