Why do older gay men prefer younger gay men?

It is simply a matter of preference. In my case, I was pressured at a young age that being gay was wrong and that I should only date women. This led to disaster after disaster. Now that I am older I have overcome the social stigma, and finally come out. I want what should have been mine in the first place. So I guess I am starting out my life over again, but I want to go back to when I was a younger man and find another younger man. Is it cognitive dissonance? No. In my mind I am still attracted to younger men. Hopefully I will find a young man that appreciates the stability and maturity of me and we can be happy. I see it happen a lot, so I am not without hope.
