First, if he gets off to quick he is excited about you and just cannot contain himself. Next, don't get frustrated. Nicely and lovingly tell him you still need something for your desires. Then tell him what you would like for him to do. If he is a loving husband he will do whatever you need to fulfill your needs. Do not get mad and talk smart or make fun when he messes up. It will only make the problem worse. I believe with the right attitude you can get him back in the mood for a second try and it will take longer the second time.
