I have never been the type of guy to last A LONG time as it is. Usually the first time would go quick but 2nd/3rd would be good. I am engaged/living with my fiance for almost 6 months now. Yes we go without and always have. The problem is I think I am getting worse. Even when we go twice the 2nd time can be quick. What could of changed? how does one get worse? what are some tips/tricks to try? I know about trying to clench that muscle but what else?
