What is the best way to increase stamina, or prolong ejaculation. I have been with my wife 13 years and it seems that most times we have sex it only lasts 3 to 5 minutes before I cum. I know that this is lately making her mad. I have tried the masturbation excersise, and I go slow and have to stop sometimes to keep from cummin but when she gets going and wants it fast and deep I blow with in 1 minute. Is there any creams or OTC pills that actually work? I have heard vagisil works but it will numb both partners. I wont her to enjoy it and have me last longer.. Thanks for the help in advance.
