NO you do not start sleeping with someone else . Make sure your wife does not have any health issues , would have been nice if you had thought of her having a possible health issue before asking if you should start screwing around on her . I am always amazed that the first thing Men think is should I go outside the marriage and not I wonder what is going on with my Wife she is ok . If she is healthy then use some of your excess energy towards her . Sex to women starts in her head , so start there , talk to her , romance her , wine and dine her , make yourself just as irresistible as you were when she married you for LIFE . Get some counseling if you cannot get out of her what is going on . If you decide to do none of this and do go outside the marriage , be prepared for the heartache , the betrayal and a possible divorce . If you were my husband and went outside the marriage , I would divorce you .
