The problem is that you were probably not banging 9 or 10s even back in the day, let alone today. What us average people (compared to models or the super rich) consider 9 or 10's is probably not really 9 or 10's. And as you get older, the chances of you being with 9 or 10's becomes less so.
I always thought that as people get older they care less about looks and more about personality. Obviously you still need to find someone youre attracted to. At this stage in my life, if I wanted to get married, I would just like to find someone who is not going to cheat on me. Seems like thats impossible to find these days.
