Very sad statement, "who cares that you need a woman to help you get it up" What would you recommend other than a woman or better than a wife.
What he is saying is a real live wife is much better than some pictures on a screen or even revolving relationships. The truth is in a sex obsessed culture, long-term married couples generally have the most satisfying sex life, because it is not just about pleasure. Sex is about true intimacy and caring for the other person, and good sex flows out of good relationship. It is very unlikely that Fred's wife would initiate sex unless they had a good relationship.
PS. I have been married 14 years and also have a very satisfying loving relationship with my wife that includes very enjoyable sex.
