I'm not very big nor do I last very long in bed is there away I can still satisfiy my wife sexually?

Certainly. Satisfying your wife in bed does not depend on genital size alone -- or even on intercourse. There are many sexual activities that creative, loving couples can enjoy together. Ask your wife what she likes, along with whatever else you're doing. Remember that she probably wants to satisfy you too. Marital/sexual counseling may also help you both. If concerned about yourself, see your doctor.
