Well, you have already said you have married and had children, so getting laid isn't a recreational pursuit (it is still one of my old favorites, but certainly I have others).
So aren't there things that you simply enjoy and look forward to doing? Like watching your child develop, creating projects that you can do together with him or her-like building a model sailboat, or teaching them how to ride a bike. Don't you like thinking of things that would surprise your wife and make her happy, or planning a family trip together, or creating activities for your family to do together. And what about your own developmental projects, learning a new language, training for a marathon, learning to oil paint, volunteering at a charity, going on a safari....
All kinds of people, in much less developed places than America find a point in life of simply learning and doing things. I read someone once said that the reason a God created tragedy and hardship, is because without it people would do nothing useful other than having sex and sleeping. Having said that, I don't see anything wrong at all with having a point in life of looking forward to doing the next fun thing.
Maybe the point is not wasting so much time looking for a point. Or how about just trying for improvement.
